My biggest issue is dealing with the same behaviour cropping up in different contexts and with different students. Students don't seem to get that S would probably cry if I spoke sharply to her, while M won't notice me at all unless I speak sharply to him. So M figures I never discipline S, because he doesn't see me give her a teacher look that works - all he knows is I don't speak sharply to her. He sees that as unfair because it's not equal. He truly believes that I never discipline half the class, because he's always talking so he doesn't notice me quietly calling their attention back.

I've used the, "I've done nothing to deserve that disrespect from you," in the past. It only works on the kids who truly believe I'm trying to be fair. That's most of them, but it's not the M's of the world. They believe the world is out to get them, and when they set out to prove it, they either find or fabricate ample evidence.
