how do you handle when you have to be with someone whom you hate

I come across the same awkard situation as you do.I must confess it is a really tough feeling because it's a question of your mind and feeling! The way I myself deal with this situation is firstly trying my best to avoid getting together with him or her even in a few minutes,but make sure that you don't hide yourself from him or her on purpose because you needn't.If you have to face the person,OK it doesn't matter, either.Try to act yourself in a normal way and consider him or her invisibly.Maybe it does work. Of course those are my personal opinions,and I am happy to listen to the ideas from other genius!

Well what i do if I am force to be around someone i hate, is I entertain myself by trying to set them on fire with my mind, obviously this doesn't work, but it's amuseing and it helps you deal with how much you hate the person without actually yelling "I hate you." and throwing something at them......or whatever your natural urge it around thier person.

I try not to put myself in situations like that. Maybe you could change seats with someone who doesn't mind sitting with him?
