you and matt hate eachother, you used to be best friends, and you've known eachother since you were 6, but something happened that made you two hate eachother (you decide what happened). Matt really likes to get on your nerves and piss you off, you hate him. he hates you.. or at least he thought he did?

Matt is sitting behind you in class, and he throws a paper ball at your head, him and his friends let out a chuckle, and you turn around, looking irritated
