A Friend's problem

Last year I got suspended for helping a friend.
This year I might get suspended for helping a friend yet again.
The same person is causing problems with my friends and I don't like it. This person, we will call her Camel, just so we don't name names, is being a total bitch to her friend. Her friend, we shall call her AntEater (cuz I like them), is wanting to do something other than robotics on the day of a competition. She also wants to be in art club. Camel and HER PARENTS are giving AntEater a whole bunch of crap about this. So AntEater is thinking about quitting robotics because of Camel. I seriously listened to Camel tell her parents that AntEater might not be going to the robotics competition and Camel's mom left the room to go to the art room (since art club was going on) to talk to AntEater about it. And by talk it probably wasn't a very nice talk because Camel's mom is worse than Camel is. Camel and Camel's mom are BITCHES.
I feel like I can't let them bully AntEater around and yet at the same time if I were to try and help AntEater I potentially will end up getting suspended because my school suspends people for helping friends. That's how it works I guess. Life isn't far. That's all I feel like saying on this topic now.
