Tried to be ertive but ended up in a disaster!?

If you have been cool with him before, maybe he was just having a rough day. It seems the teachers know a little more than they are letting on because any teacher I know would have stepped in and stood up for you just basically speaking your mind. Dont let it get to you. You can apologize if you want to, Im pretty sure if you did than he would apologize back for flipping out at you. ( Again this is uming you were all cool before this incident )
