Personality

There are four high school girls I can't even stand. Three of them have MEGA-attitude, and I'm not sure what to do about it. I think I'm going to just start kicking them out. Maybe once they've had their 7th or 8th detention, they'll get the point. I need to go back and take another look at my discipline policy. Or be more consistent with it. And it's JUST THOSE FOUR!!!! The rest of them are fantastic. HELP PLEASE?!?!
