Author's Note: Please excuse my prolonged absence I have been extremely busy as of late and my lack of updates was unforgivable. Rest assured that I have not given up on my other story but this idea was just too good to pass up. This is sort of a prequel to my other story so please enjoy it. Both stories can be read alone or together whichever you prefer. To those of you still reading my other story an update should be posted within the next week. If anyone has any ideas about where I should take the story, or anything you think I should add feel free to message me or leave a review

The Diary of Minerva McGonagall , Hogwarts Transfiguration Professor and head of Gryffindor house.

September 1st

I can't believe that Albus has allowed that wretched deatheater to teach at our school. How could he honestly allow someone that had been so awful in joining the other side to TEACH here at our school? He was a known death eater for goodness sakes. Albus must really be out of his mind. He has said that Severus is a changed man, and that he has brought us important information for the Order from Voldermort's inner circle, but how can he be so sure that what Severus says is true? How can he be sure that Severus will not take information from the Order and give it to the other side? I know that Severus and I used to be friends back in our school days together, and I will even admit that at one point in time I really did have a bit of a crush on him, but now after all that he has done, I can't believe he has been allowed back. I despise the fact that he was allowed to come back here, and teach. All I can say is that I do not trust this Severus Snape, not one bit.

September 3rd

He is a horrid teacher I have heard, yelling at the students and scaring the first years, it is something that is never done. I've never met someone as strict as he is and so hard on the students. I believe that already the children have come to fear him, and get out of his away immediately when he walks down the hallways. He says the students aren't well enough prepared in their potion making skills and has changed all of the requirements for his classes. To be in advanced potions, they must have attained a perfect on their O.W.L.s. Does he have any idea how few students can attain such a spectacular grade? In our year, he was the only one to receive that mark. I do admire his high expectations though, he can't just let the students graze their way through school; they must work hard and go above and beyond.

September 15th

Severus and I have started talking again, if only to be civil with one another, I refuse to accept Dumbledore's word that he is a changed man. It would be easier to accept if he gave me a reason why Severus changed sides so suddenly, but he says that it is between Severus and himself, and always leaves it at that. I know that I should trust Dumbledore and that I probably should not be so hard on Severus. I just fear for the sake of the order, and for the sake of the students and all of our kind. Until He-Who-Must-Not-Be-Named is gone, I will not allow myself to place trust in Severus.

September 21st

Try as I might I find it almost impossible to hate this man, my dear childhood friend. We were as close as two peas in a pod as one might say. The only other person he was that close to was Lily Potter. He had a fierce devotion to her when he was younger, even after their friendship broke off he still cared for her and tried to protect her. I have a hunch that he may have become a deatheater, to impress her after James had caused their friendship to break off. I have a feeling that Severus may have even loved Lily at one point in time. I regret that I could not have been closer to him at that point in time, in which he was most vulnerable, I could have helped him, guided him. Instead I watched from the sidelines sitting there like a dumb fool, not brave enough to intervene and help my dear, dear, friend. At this point I find myself wondering if Severus would take any interest in renewing our friendship just like old times and joining me for a nice cup of tea. I think I will ask him, maybe we can even play a game of chess.

September 25th

I'm glad that I had invited Severus to tea, we ended up having a splendid time over tea and a game of chess. It was so good to catch up and talk about old times, I have no idea why I was so reluctant to accept my old friend again. Though he is a bit sarcastic, and still makes some jeers he is truly a kindhearted man. I have a feeling that he puts on the façade during the day to get the students to listen to him, and he wants to be viewed that way. Similar to the way I am around the students and most of the staff. Around Severus I feel that I can truly be myself, and feel comfortable that way. I feel a sense of security with him, a feeling that no one else can provide. We have decided to have chess games at least once a week, alternating between his quarters and mine.
