First off .. she's a teacher, so her saying she could have sent you to Saturday school isn't a threat .. it's just a fact. She could have. It doesn't mean she should have or really would, or even that she didn't over-react to simple doodling (what were you doodling anyway? It sounds like she may have seen something on the paper she was offended by). But still, the fact remains .. you are a student, and she is the teacher .. and there are some not-so-great ones out there who don't understand kids very well. Just try and let stuff like that slide ... if she's on a power trip, and you really did nothing offensive, then don't give her the satisfaction of reacting. Just hand over the paper, and when she says stuff like, "You are lucky ... " just nod like, "K .. I heard you, I'm going to go now." Don't "slam" out of somewhere .. just leave. Do the time and just follow her rules .. try not to sweat it so much. You have to analyse your reactions to things and be honest with admiting if you made things worse.
