Dear Mr and Mrs Dursley,
I am writing to you concerning the new addition to your family; your nephew Harry Potter. I most sincerely apologise for any inconvenience caused, but am glad to see that all appears well.
As you know, Harry coming to you was the result of a terrifying attack on Lily and James Potter. It was a miracle that the boy survived, and he will be famous in the wizarding world. Naturally, he should be brought up in a happy family atmosphere, regardless that you are non-wizarding folk. I assume that you will provide sufficiently for him; we will do our best not to interfere in your home, though Harry will be under observation from time to time, to assure that he is still safe.
I trust that you will honour your sister's memory, and treat Harry like he is your own.

Yours sincerely, Minerva McGonagall

Her hands trembling slightly, Petunia placed the parchment and her silver letter opener on the coffee table with a dull thud. Their kind would be watching her house… it was more than she could bear.
Shaking her head to clear her thoughts, she lifted a second envelope and cut it open, as she had with the other. This one did not contain parchment, but a letter with a familiar header at the top. 'This is all I need…' she sighed, reading it through. Her school was having its fifteen year reunion… All the people she had known at the age of sixteen would be there. How often did they have to have these events? The ten year one wasn't so long ago, and still they dragged her back; her past could never rest in piece. 'Or pieces,' she thought miserably, remembering how her world had slowly fallen apart during her time there; her O level results discarded next to Lily's OWL and NEWT certificates.
She sighed and got up, busying herself by clearing the kitchen. Her husband looked up from his newspaper and greeted her cheerfully.
'I found some of yesterday's post, dear, it must have been a late delivery,' she said, making conversation in reply.
'Anything interesting? I did wonder why you were taking so long to come through!'
'There was an invitation to another reunion at my school,' she said quietly, turning back towards the door.
She heard Vernon rise and follow her. 'Well it will be nice to see all of your old friends again, won't it?'
Petunia merely raised her eyebrows, and then sighed with disbelief and defeat. 'You don't understand, do you?' Her husband's blank face was enough of a reply for her to continue, 'It's stupid, whenever I see all the people from my past... I want to prove that I'm not how they remember me.'
'Not ho-?'
'I want to be cool, OK?' Petunia felt her voice waver as she spoke. 'It sounds ridiculous, but I was a complete waste of space my whole life and I want to prove that I have moved on and become something.'
'But you have mo-'
'-and people from my past turning up to criticize me and stir up troubles, it's not f-'
'Petunia, I-'
'It's not fair Vernon, and I won't have it, I won't have it any more!' Surprised at how quickly she had become upset, her hysterical cries rang dully in the neat living room of number four Privet Drive. It seemed strange to think that so much had already happened under that roof.
Dudley turned over in his sleep, causing the pram to groan and creak ominously. Petunia instinctively flicked her eyes over him, before raising her hands to her head, and pressing her fingers to the temples.
'Petunia…' Vernon said gently, touching her arm. She raised her head to look at him, her wide eyes brimming with tears. 'Is this about your reunion, sweetheart?'
Petunia sighed and looked to the floor. 'It's not just that…' she trailed off and stubbornly stared at the carpet. Vernon had learned from experience not to question his wife when she was on the brink of explaining, so sat down next to her on the sofa and waited for her to speak. Sure enough, she looked up at him and said 'I received a letter from Minerva McGonagall today, Vernon.'
The effect of such innocent words was quite surprising. Vernon's face contorted to resemble a confused or perhaps distressed rhinoceros, as he struggled to maintain a calm exterior. Eventually, he managed to splutter, 'What… did… did it… say?'
Petunia explained to him the contents of the letter in brief; how the wizarding world would monitor their nephew, about his importance to them, and how they would try not to interfere with family life. When she reached the part about honouring Lily's memory she sounded bitter and positively furious.
'How dare she tell us how to behave, Vernon!? After leaving him on our doorstep like that!' Her voice had become steadily shriller again, and Dudley's movements in the corner had become louder. Calmly, she stood up and straightened her apron, before striding over to the pram, speaking softly to her son.
'Are you awake, my Dinky-Diddums? Are you hungry? Aren't you the most adorable little boy in the whole world…?' She groaned slightly with the effort of lifting her colossally large son, before learning him against her, bobbing him up and down.
She continued to speak in a soft voice, but to Vernon, who had remained silent since his previous outburst. 'I suppose I'll survive, it's just that I'm so tired of being me…' She returned Dudley to his pram and pulled the blankets neatly around him. Turning to face her husband she was a little surprised to see him directly behind her.
'Do you remember your last reunion?' She looked up into his face as he brushed her hair behind her ears and continued. 'You were just as worried that time, I can still remember you exact words-'
'-"I don't want to go back; I'll never be good enough for them…"-'
'-"I've always been unwanted and I just want them to like me."' Petunia was staring at the floor trying not to let the lump rise to the back of her throat, when Vernon added softly, 'You told me about what they said to you, the things they-'
'They told me that I was a waste of skin,' Petunia spat out angrily. She couldn't hold back the tears any more, as her throat cracked and squeaked. 'I didn't want to go back because I'm not cool or pretty or anything that they are. I'm just a nobody, I-'
'I think that you are the most amazing woman that I have ever met in my entire life,' said Vernon quietly, lifting her chin so that she was forced to look away from her slippers, that had been so interesting to her. Her eyes shone wet with tears and her lower lip was trembling. She would not tell him about Lily. Or James. This thought pushed the first tear properly out of her eyes, to journey down her cheek leaving a salty trail of regret and remorse behind it.
'Hey,' Vernon used his thumb to gently clear her face from the fountain of tears and smiled. 'You are a fantastic wife to me, a brilliant mother to Dudley, and,' he added as an after thought, 'wonderful with Harry.'
Petunia felt her heart leap to her throat with these words. How could he have found out? She felt so deceptive and unfair to him. She swallowed what felt like her entire digestive system in the back of her throat and let Vernon continue.
'… You welcomed him into your home when hundreds wouldn't have. What a noble thing to do!'
'Good,' thought Petunia, feeling relieved. 'He doesn't know how much I really care for Harry.' She still felt fallacious, and very guilty, but at least safe in her secret.
'Petunia, sweetheart?' Vernon brought her back to reality, looking searchingly into her eyes. She smiled in response and he kissed her on the end of the nose. She felt herself genuinely smile as he chuckled, 'Besides, the only way you won't look good is if you mask the real wonderful you, for a superficial person like they do. Let them know the Petunia I know.' He hugged her before checking his watch and gasping, 'Crikey Petunia! I'm supposed to be meeting Mr Nelson for a round of golf!' He kissed her swiftly on the cheek and motioned to Dudley, 'Take care of my little man, eh?'
He swooped on his golf clubs by the fireplace and was just closing the door when he turned and questioned, 'Are you going to be alright, sugar?'
She nodded and smiled adding, 'Have a nice time darling, but don't be late – its pork chops tonight!'
'My favourite!' he grinned, lifting his hand in farewell and pulling the door shut behind him.
Left alone with her thoughts, Petunia settled on the sofa with her head in her hands. 'The real me…' she moaned, shaking her head slowly. 'I can't live like this any more, I don't know who I am.' Looking up, she registered the letter still on the table and stared at it for a while. Sitting forward, she found notepaper of her own and her favourite fountain pen. She knew how to sort her mind out; she was going to write to Dumbledore.

Thanks for the reviews I've got, much appreciated! I'll keep writing with more reviews, so please, let me know what you think!
