if you can't teach and raise your kids with good manners don't take them to school. what the teacher did was 100% wrong no question asked, but seriously I saw some kids behavior that is completely annoying and where every they go they leave disaster behind them.
It is the same thing when parents leave their kids to play outside in the streets un attendant and after getting killed in an accident they go crying about it or the ones who leave their kids at the mall (to hang out) and never return home!
Seriously some parents think that the world is responsible for their kids..
