In 8th grade I pulled the fire alarm and blamed it on a guy I didn't like
Are you kidding? What did he do that made you blame it on him?
He was being really to me, so I decided to pull a prank on him.
Even if you're really mad at someone you shouldn't go blaming things on them that they didn't do. You should do your best to own up to your mistakes and not try to pawn the blame off on other people.
I don't care. He was mean to me so I got him back.
I'm sorry that he wasn't very nice to you, but pulling the fire alarm and blaming it on him was very serious. I think it would have been better if you had talked to a teacher or other adult about how he was treating your poorly, rather than cause him to get in serious trouble.
