Most bullies are quite retarded. I mean, dalekman, your name is Nikolai, and they make Dickolai out of that? How original. Christ, shame bullying isn't a GCSE .. they would have gotten full marks.
My point is bullies are thick, and use every old trick in the book - mimicing, physical bullying.etc. If you're gonna bully, do something intellegent -_- not that I'm agreeing with that kind of behavior.
I live in the UK, and most anti-bullying measures in state schools are aboslute sh*t. They do nothing, and make you out to be the one who is aloof.
All my advise is stand up for yourself, and make sure that, when you achieve higher than they do, they know it.
