Be tough. It will be very, very hard as these folks are trying to push your buttons. You can't let them intimidate or make you feel bad. That seems to be what they are trying to do. Get headphones, shut them out, don't try to beat them at their own game (they will win, cause it's their game). Take the high road if you can. Maybe at some point you can have a conversation with them and work out the differences. You don't know me and I don't know you but it's a lousy situation to be in. Good luck!!
