A/N: Friday, the 13th is my lucky day (one of such days was very lucky), so let's see which good events can happen with someone on that day.

Another few days have passed. Among other things, the witches studied. Needless to say, 'constant vigilance' was their favourite. It wasn't much of a study, though. 'Constant vigilance' didn't limited by the evenings.

'If we'll want something in the morning and we shall have time, "constant vigilance" has to be on. We'll cast silence spell again. Of course, spells didn't last long, so there's no way for a spell cast in the night to work in the evening.' Constance said on the first evening after the witches came back to the Academy.

'Also, alas, there should be no real interactions between us unless we're alone completely.' Imogen added and sighted.

'You should say these words to yourself.'

'Consider how emotional you became and how easily you can lose control when we're alone, it's not unnecessarily to say it to you too.'

'Firstly, you're a reason why I became very emotional; secondly, when we're alone, you cannot keep calm like me, and it's even harder for you sometimes.'

This day started as always.

'Do you want "constant vigilance" to be on?' Imogen asked by her usual voice, not trying to change it even.

'Somebody's very impatient.'

'Here are two "somebody".'

'Words without proofs are nothing. You suppose the fact that we're lying in the bed is enough for me to lose a control.'

'Of course, I know your emotions too good very often.'

'You're absolutely right. It's a good proof.'

'Can I be first today?'

'Yes, but only if you put a necessary spell.'

'I would do more if we needed something else.'

'Think as if you said it in advance. I may remind it you in the future.'

'Don't forget it, please.'

'I shan't.'

'It's good; because I like to fulfil my promises, even if it's later.'

Time didn't mean anything for the witches then. It wasn't matter what time is it or how many time had passed since they started their 'activity'.

'. . . What you should say in the end?'

'Thank you, I suppose. I really mean this. Thank you very much.'

'I hope it was a joke. I'm glad you liked it, though.'

'Yes, it was a joke. I should show how much I want to do it to you. It's not only my reply to your great actions, of course.'

'. . . It was absolutely wonderful. Doesn't it great to have such an amazing girlfriend who can do such wonderful things to you when she's very emotional?'

'It's great, but here's no need to tell me about yourself; because I know this all and even more.'

'I meant you and only you.'

'I know, dearest; it was a joke again. Really, I can say everything of this about you.'

'It proves that we meant for each other.'

'You tried very hard for it to happen, in spite of you did it unintentionally.'

'You didn't leave me a chance not to. As you know, I was fascinated by you since the very beginning. You had had a place in my heart since that moment. I thought sometimes that here's no possibility for something between us. All right, there was one possibility which, however, guaranteed nothing. You were single, a gold star lesbian— you wasn't ever attracted to men. Needless to say, you had never had a boyfriend, but you didn't have a girlfriend ever too. Of course, I had no idea about your orientation before you confessed to me. You were single, but you're not absolutely and we both very happy because of this fact.'

'Idgie, if think about our confession which happened when you were in fifth semester. . .'

'Form mother, I do remember it very well.' The future teacher could not resist calling her now closest person the same way as she did on that memorable day.

'What's about that book?' Constance asked a bit teasingly, knowing that that book was their favourite, but she did not know completely how Imogen will react.

'That book!' The lass said happily and smiled. Then she was thinking about something a bit. Very soon, the lass realised something wonderful she was more than gad to share.

'The little witch. . .' The Potions mistress could not resist calling Imogen the same way as she did on that day. Moreover, she reached out Imogen's face and tenderly stroked by forefinger a bit.

'Aha, the book by Otfrid Preussler. Dear, today is Friday. Do you know what it means?'

'I do know something else about this day. Must I share this or smart Imogen have thought about this too?'

'I hope what I thought about is the same what you mean, but I don't want to say it at this very moment. I want to do something at first.'

Imogen stood up and approached to the chair where were lying her trousers with a small spot. The P.E. teacher could not resist. 'Constance, look here.' The younger witch set her fingers and cast a spell. The trousers have become clear. 'This spot seemed unable to be removed by a non-magical way.'

'Maybe, you needed to put effort for a stain to be removed?' The potions mistress asked jokingly; because she knew why Imogen used magic.

'I wanted to break some stupid rules; in fact, I'm not this little witch. I can conjure on Fridays, on Fridays the 13th especially.'

'Another proof that we think about the same sometimes.'

'Yes, such a good proof.'

'I read somewhere wonderful words. "Someday, someone will walk into your life and make you realise why it never worked out with someone else."'

'I didn't have someone else, but I know why it worked out between us. It's everything we need to know towards this quote.'

'We know it very well.'

'Const, I have a great offer for you.'

'What is it?'

'Do you want to fly today?'

Constance couldn't say anything during few moments; because conflicting emotions hindered to make a decision. 'What's about "constant vigilance"?' The witch said finally. It was most rational thought.

'Today is the day. It's a special day, isn't it? Do you want to prove that we don't believe in stupid omens? I have nothing against omens which are observations, but this one is very stupid.'

'I do agree with you completely. This omen is stupid really.'

'Do you want to fly after noon today?'

'Yes, your offer accepted.'

'. . . It will be first time when we'll be flying without a concrete destination.'

'Meanwhile, there near the Overblow Castle appeared a woman and her daughter. The girl was ten years old; she had black hair and brown eyes. Also, the girl had a toy— a black cat named Blackie which had green eyes, white whickers, and a big brush-like tail. The cat's ears where black on the back side and white on the front one. The travellers lived in Scottish city Aberdeen, and decided to explore some parts of United Kingdom. They ride a train, and then go out and walked to their destination.

The castle drew the females' attention. The girl was interested especially.

'Mummy, can we go closer? I want to look at the castle. It seems very beautiful from distance.'

'Why not? I'd like to look at this old building too.'

'. . . Good luck to us, then?' The Potions teacher said when the witches was about to sit on broomsticks.

'Const, why we need to wish us good luck?'

'We didn't want somebody to see us?'

'If a witch will see us it won't be bad, will it?'

'Don't be silly, Idgie. The possibility for witch to accidentally be here is one to million.'

'It's not a silly thought. Here can be such a possibility.'

'We'll see.' Imogen said right before they sat on broomsticks.

'. . . Const, look down, there's a girl with a woman. Maybe this girl is a witch.'

'The chance is one to million, remember? Why you didn't say the same about her mother? According your theory, she can be a witch too.'

'I don't think she's a witch. I'm feeling intuitively she's a non-witch.'

'You have no proof, darling. I hardly believe you will ever have them. If you're so sure, fly to them and say hello.'

'It's not a good joke, darling. Anyway, even if I shan't proofs tt doesn't matter.' Imogen replied and smiled to the girl who looked at her not able to look away. It was not the smile Imogen gave to her beloved which when they were saying goodbye to each other. It was a different smile. It was 'I don't know who you are, but hope your biggest wish will come true' smile.

'Mummy! They're. . . they are. . . witches!' The girl was unable to hide her excitation.

'They who?'

'Two females in the sky, didn't you see?'

'Don't be silly, Mary. You read too many fairy-tales and imagine things which don't exist.'

'No! I don't imagine things. I am sure, I am right.'

'All right, Mary, give me proofs.'

At this minute, the witches had been hidden behind the castle, so the poor girl had no proofs.

'Here were two witches in the sky. Witches do exist.' The girl said to herself. 'I wish I had the proof, but I know I'm right, no matter if mother believes me or not.'

Mary McDonald looked at Blackie and sighted. 'You're the only one who makes me a bit close to a real witch. It's not enough, but it's something. Alas, having a toy black cat can't give you ability to conjure.'

The girl had no idea what will happen in a few years. She did not know that her guesses were not only right ones, but it was much more. She didn't know about this yet, but she'll know. Don't be shocked, Mary. You're a witch too. This witch who smiled to you will be your teacher. Many witches would do anything to be a pupil of such a wonderful witch. You're lucky Mary, but you have to wait until you know the truth.'

'. . . Nor Imogen nor Constance discussed what happened. For Constance, it was something that had no sense and was pointless, but for Imogen it was piece of happiness— the very good proof why Fridays the thirteen were very lucky for her sometimes.'

'Do you want to fly to Pentangle's Academy? It situated only a few mountaintops away from Cackle's. Not to mention, there's nobody here.'

'How you can be so sure? Cackle's supposed to be empty, but it isn't.'

'I know teachers of that Academy. All of them can't wait to spend holidays with family. They will never come back to the castle earlier.'

Pentangle's Academy was situated in an old beautiful castle. The witches flied around the building few times to completely enjoy the view.

In the middle of flying, Imogen and Constance made a break to eat something. Happily, they took food, so they didn't need to use magic.

The witches saw many beautiful old buildings on that day. When they had came back to Cackle's, they both realised one thing— no matter how many old buildings they will see, this castle will be their favourite.

'. . . Do you want to finish this wonderful day by something really wonderful?' Constance said after dinner.

'"Constance vigilance" will be on, I hope?'

'Probably, if you want it so much, love.'

'You know how strongly I want it.'

'Well, in this case you know how strongly I want this to happen.'

'It was a very good addition to the wonderful day. Of course, the witches needed no spell, but it was a rule. They had to use using a silence spell in the castle, so it was necessarily to use it even when here's nobody at the Academy except them.'

XXX

Two years later, Mary became a pupil of Miss Cackle's Academy for Witches.

It happened very strangely, but the girl was first of the family who knew the news. Mary had got the best proof she needed two years ago. 'Maybe, this lovely witch will be my teacher.' The girl thought with hope.

Mary entered the living room, smiling.

'I am a witch,' the girl said and gave her mother a paper which proved her words.

'You're who?' Father didn't realise at first that it's not a joke.

'I am sorry, I was wrong; in this case, congratulations, dear.' Mother apologised.

In spite it happened two years ago, Mary was happy. She won eventually, and there was no way to deny her mother was wrong.

'Really?' Father wondered. 'You'll be able to conjure and cast spells? You'll be brewing magic potions also, yes?'

'Yes, Daddy,' Mary said proudly. 'I'll be able to fly on a broomstick also.' 'I wanted it since that memorable day— Friday the thirteen of August two years ago.' The girl added inwardly. These were her private thoughts, and she didn't want to share them with nobody except that lovely witch who may be her teacher.

A man opened his mouth to say something in reply, but did not find right words. He was shocked.

'Yes,' mother agreed, looking up from the paper in her hands. 'Mary needs witch clothes also.'

The girl turned to her father, 'How you'll explain why I could make cold tea warm only after a minute of holding cold mug with tea, although my hands were rather cold? It was two and a half of a year, it was January.'

'I forgot about this case. If you would not remind, I could easily forget; it was very strangely. I tried to make my tea warm like you did, but my attempt failed. I wondered how you were able to do it.'

'I'm a witch, that's why I warmed my tea. I had no idea about who I am then, that's all.'

Later, when Mary McDonald will start to study at Cackle's Academy. . . She will be unable to resist saying what she very wanted to say.

'Miss Drill, I think I saw you before.'

Imogen will look at the girl not understanding what she has said. 'Mary, you mean you saw me before?'

'Yes, I think I saw not only you. It was the thirteen August two years ago. Mother wanted me to explore some places of United Kingdom, and it was the day when we appeared near Cackle's Academy. Of course, I didn't know anything about this castle. I saw you in the sky, but when I wanted to show you to mother, you had hid behind the castle, and I had no proof. Miss Drill, how strongly I wanted your smile to be a sign of a hope for something good.'

'It was, and I very wanted too. The other person I was in the sky with. . .'

'It was Miss Hardbroom.'

'Yes, it was she. I said to her that we may meet a witch, consider it was Friday the thirteen, my lucky day— that day was one of very lucky Fridays the thirteen.'

'I can say assuredly it was my lucky day too.'

'You saw me, a witch, even if I had no idea who I was; therefore you won.'

'Mary, you had the proof that you won since the moment you took the paper from Cackle's, and your mother lost.'

'Yes, I was so happy. Father didn't believe me at first.'

'I suppose, his behaviour changed once he realised who his haughtier is.'

'Yes, but I don't going to turn him into a frog, though.'

No matter how good Mary McDonald was at any subjects, Flying was her favourite. Why? Don't you want to ask Mary? She has answers for any of your questions.

'I saw two witches in the sky. One of them smiled to me even. I don't know why it happened, but I felt something. I thought I shall never be able to do it. It was an urge to sit on a broomstick and up in the sky. Later, when I knew who I am, I couldn't wait fist Flying lesson. When I was up in the sky for the first time, I realised that I had never felt myself so wonderfully. I liked Flying since the day I saw Miss Drill and Miss Hardbroom in the sky, but I almost fell in love with it since the moment I was up in the sky. Thank you so much, Miss Drill.'
