Believe it or not, teachers face flippant assault charges every single day at the hands of parents who behave like catbirds over their newly-hatched eggs, thinking there's nothing in the world more precious than their little Amy or little Tyler, and that the entire school system needs must bend over backwards to accommodate the little dears exactly as their parents pander to them at home.
