What d hell!

A terrible thing happened to me. I dont even think that it will happen but maybe, I think, he is angry to me or just want to get attention. . but it is not the good reason to do such thing as changing my score from not-that-high and passing score to a failing mark. .
We had a test on october 06 and we have to check it, october 07. .
After checking, our professor announced our scores and I heard mine. I had low mark but i don't questioned it because deep inside I know i didnt review. But after that day, October 08, 2007, when our professor gave our papers. I felt upset and i even cried. . He changed my answers in almost 10 items. It is so ridiculous! My seatmates can witnessed that. . That time I was angry but I prefer to cry so that whenever i want to find out who did it, I will not going to get angry because I'm not that kind of person who likes to attend wars. . And I want to find out why he did such thing. . .
Now, I knew who is that person and next week, I want to talk to him. And I want to ask "why?". First, I did not expected that he can do that.. Some people said that he is kind and they were shocked when I told about
