wally, dont back down from your comment, own it. ive been a screwl teacher myself, and its not easy. this group of newly minted adults,{a lot of them, not all}, can be lazy and spoiled because the parents want to be a human shield for them. hopefully things will change for the better, if not, im going to invent a spine strengthener for most young men. hey, wouldnt a 2x4 duct taped to their back work? I think this would help them drive the family car when they reach that age. and those that know me well know i have a obtuse sense of humor, and you dont have to wait till my back is turned to call me an idiot. Express yourself to my face, strenthen that spine, i take constructive critizism everyday, hopefully it will make me a better person. Try it sometime.
