Honestly, can 8-year-olds really sexually harass each other? And if one 8-year-old pinches another's butt, is going through a bare-light-bulb-interrogation really the appropriate way to handle it? My elementary school teachers probably would have handled it thusly, "Keep your hands to yourself." And if we didn't, we'd probably have had to sit on the bench at recess.
I don't see how treating an 8-year-old's action the same as we would an 18-year-old's transgression does any good for anyone.
