How to Forget a Granger Every Month

Chapter 1.

Hermione Granger woke up on the 27th of March and groaned as she has done for the past two years. As usual since the end of the war, she has gotten out of bed on every 27th and wished it was already the first day of the next month.

She could not believe that she had actually agreed to do this in the first place. Then she remembered why she was doing it, and sighing she proceeded to take a shower. After a wonderful breakfast of pancakes and coffee, she took her trunk and Apparated to Hogsmeade where she joined a group of students from her seventh year, including Harry and Ron.

She smiled thinking how much her friends had grown up since Graduation Day. Harry, after defeating Voldemort the day after the end of his seventh year, was still doing well in his Auror training while Ron had been playing professional Quidditch, as a beater, with the Chudley Cannons since he finished school and the training with the team.

She and Ron had been together from the their sixth year until his demands had been too much. Hermione had gone to Oxford Magical University and was happily studying for a combined degree of Charms and Potions but Ron wanted her to watch him playing every Sunday even though she had to study, so for different reasons after two years together the couple had decided that they were better off as friends.

Now Ron was going out with Lavender, and from what Ginny had written her, he was really serious about the girl. Lavender was much more compatible with him than she was, and Hermione had been happy to know that he had found the right girl.

Regarding Harry and Ginny had been married for a year and they were a couple defined by many as perfect. Sometimes Hermione wondered if she could ever find someone who accepted her with her many faults and vice versa.

Now, back to her imminent problem. She sighed, imagining what was awaiting her. She was going back to Hogwarts for her last class of Potions and the Graduation Ceremony.

She was very frustrated that nobody had yet found a way to break the curse of which Snape was afflicted.

Severus Snape had been a hero of the war; he had saved her, Harry and Ron during the final confrontation. Almost all the witches and wizards of his generation owed him either a life of a relative or their own.

So when Albus Dumbledore had called the former seventh year students of all the Houses which had been graduating her same year, she had gone to hear what he wanted.

She remembered that day, almost two years ago…

Albus had cleared his voice and then to the many witches and wizards gathered in the Great Hall he had said, "Dear friends, I am here asking you a favour. I know that now you are all free from my clutches," many laughed and she just nodded and smiled.

"I am sure that you just want to go on with your lives, but there is a problem. One of the our most valiant fighters needs your help." He paused to let the information sink in. "Severus Snape may not have been the nicest teacher you have ever had, but I believe many of you owe him your life. During the battle he was hit by a very strange curse, and until we find a cure I am asking for a little help from you."

Hermione watched the faces around her; she knew that many still disliked Snape quite a lot, yet at the same time she saw that they were all going to help as much as they could.

Albus watched the young men and women and smiled when he saw that they didn't immediately reject his plea of help… yet. He knew that after he explained the gravity of the curse many would not be so willing to help. Still, he had to try.

Hermione raised her hand. "Albus, which curse hit him?"

Albus smiled at the witch who was the smartest of her year as well as the one who had just turned back the attention onto him. "As I told you before we haven't yet found out but we know the effects it has on Severus. There seems to be a glitch in his memory, and every 27th and 28th of the month his mind is thrown back to the day of your last Potions class, the Graduation Ceremony, and the Ball."

This piece of information shook many of the former students, and they started to whisper and chatter incessantly among themselves.

Albus cleared his throat, raised and lowered his hands as a sign to be quiet again. "Now, we are working for the cure but we are asking for his Advanced Potion class to come back every 27th of the month and for the others to be all here for their Graduation and the Ball on the 28th."

Hermione and the others remained silent. She had to basically live two days of her life over and over again every month to help Severus Snape!

Now, while her Gryffindor nature was shouting at her to comply with the Headmaster's request, her vindictive side was instead thinking to leave 'as soon as possible'.

Albus studied the faces and saw that Harry, Hermione, and Draco were still the leaders. Everyone was looking at them; if they accepted everyone would follow their lead.

Harry was the first to talk. "I will help you, Albus. I have a debt towards Snape and now I am able to repay it. You can count on me."

Draco Malfoy, who surprisingly had turned spy and helped the side of the light, spoke next. "My Slytherins and I are more than willing to help our Head of House."

Blaise and Pansy nodded their consent.

Hermione was trying to find an excuse not to accept, but seeing that everyone was so willing she just nodded her approval.

Albus smiled warmly. "His class was composed of Misters Malfoy, Zabini, Weasley, Potter, Boot, Longbottom, and Finch-Fletchley. The Ladies were Misses Granger, Brown, Parkinson, Padma Patil, and Abbott. The ones I did not call should please come back the 28th with your Graduation robes and clothes for the Ball. I hope this discomfort will end soon."

Now, she was once again standing in front of Hogwarts' gates along with the other Potions students, and waiting for Professor McGonagall to open the doors and usher them in before Severus would have a chance to see them coming from outside the school's ground.

Hermione sighed. She had been sitting near Neville every month in the advanced class and they have been doing the same potion over and over again and while everyone else could almost do it in their sleep he was still exploding cauldrons as if he was a student, scared of the Professor.

She repressed a smile when she thought that every month one had to botch his potion in order not to raise Snape's suspicions that something was wrong. Everyone except her because it wouldn't be believable.

When they were all seated Severus Snape entered in the class with his usual scowl and without any attempt at pleasantries said, "Today it is the last time I will ever see you dunderheads. I cannot convey to you how happy I am."

Pansy giggled and Hermione, who was trying hard to suppress a laugh at the phrase that she had heard for the near hundredth time, could not repress a smile.

Professor Snape noticed Hermione smiling and malevolently snarled, "Miss Granger, what is it that makes you smile? Is interesting to you to know that you are a dunderhead? Ten points from Gryffindor. Let us see how you can regain them for your House."

Hermione tried hard to fake unhappiness and took a breath of relief when he smirked at her. He had believed her disappointment.

By now, all this was starting to be too much. Every month she had to hear him telling everyone how happy he was to get rid of them and she repressed another smile when she thought that the curse had really hit home. He was reliving one of his worst classes, too bad he didn't know it, but it was better than nothing, in her opinion.

The lesson went on as usual, and after Neville's cauldron exploded, she got her mark and exited the classroom.
