some crazy stories in this thread.
a recently retired MS computer teacher in my district was a pedo. he would sit all the cute girls and cheer leaders right near his desk. his tactics included the old "Ooops, i dropped my (insert writing utensil) right next to your skirt, il get it ^_^", or he would answer questions and help them by standing right over them or resting his elbows on the back of their chair. he once dropped a quarter down a girls shirt(a freaking 6th grader!) and immediately went to grab it, but the girl stopped him and got it herself. there a whole bunch of other stories but it doesn't matter. my school district teachers, staff, and school board are all so corrupt that they never believed the kids or parents and he got away with everything.
other than him, most of my teachers were either really cool, or a colorful band of idiots. one thrives on failing students and considers it a personal failure ("he didnt challenge them enough") when he has to give a student an A. another is just a freaking douche who thinks he is funny as hell (oh wow, the "cat in the blender" story for the MILLIONTH !%@#^*$ TIME!!!). i also had a teacher that literally didnt know his own material...good thing i had a few awesome teachers to make up for the bad ones.
anywho, again, im sure youll do fine. just stick with your friends and whatever you do, DONT get caught in the open.
