The thing about bullies is they get a rise out of getting a reaction out of you, if you act like you don't give a crap they'll either stop or go further in an attempt to unnerve you. Either way if you continue to completely ignore them they'll stop as it won't be fun for them to pick on you. (unless of course they get physical, them by all means give them a reaction, a punch in the face preferably.)
NONONONONONO.... thats PARTLY right. you go straight to the physical and beat the crap outta them.
Great! So then he could do something that he doesn't even have to do and go to Jail! =D Seriously, just shut up. You don't need to take it THAT far just to deal with a bunch of idiots with no lives. =P
