not as much Ginz...see in private schools most kids WANT to be there. On the average no parent is gonna pay private school for a kid that is a total fuckup. A private student knows they can be kicked from school at the drop of a hat. So in all actuality no it does not happen there...if it does it only happens once. You also dont get as much street trash in the school.
Besides it dont happen in the private school right in my neighborhood. Yeah it is a great private school. Amazingly enough the kids dont smart back to the teachers. Then again The teacher can use physical punishment or can actually make the students life a living hell till he/she is voting age. The school has a great name too....it's called HOMESCHOOLING.
Private schools must be different where you are.
