That is so scary, I would cry like right away. But do what Stacey says, I swear it will help and hey this would be a great story! Sorry, that was random
I think that you should tell a counselor or teacher, principal even. If it’s as bad as some of the things that I have seen then he shouldn’t be there, and i know that this has GOT to be hard on you to see him and have to be scared of him. Just remember your safety and the way that you feel is more important then whether he gets to work at your school. You are the one that has to go there, he can get another job.
Tell someone, please.
