One very important thing I forgot to add:
DO NOT HIT/SLAP them!! You could get into serous trouble for fights in school and ruin any scholarship chances you have and ruin chances for recommendation letters from teachers you liked. You destroy your own rep this way. It's plain stupid. yeah it seems like a kewl idea at the time, but trust me it's dumb.
Rule of thumb of life: Do not touch another person, no matter how mad you are!!!
