In my place it is the teachers who harass kids. There was no such environment that made kids to bully each other as I remember in primary and high,though psychopath seniors ragging juniors and suicides are common in colleges .
Me and my friend and another guy was playing. I held his hands my friend held his legs.We swung him to the sand heap beside and he cried and called headmaster.The headmaster beat the shit out of us using metal scale while the guy laughed at us. :|
My highschool life was good though.I almost managed to not get beaten by teachers.
