I don't think I was ever bullied and I don't think I ever set out to bully someone but I'm sure that sometimes the things I did or said could be taken that way. Hell, in primary school I used to run a sort of imaginary game where I would hand out titles (such as Duke or Lord or Count or whatever) of imaginary places and people would do things to obtain them. I can't really remember what people did for their various little imaginary rewards.
Coming from a town of only 20-25 000 people and attending one of the two major Catholic primary schools and then attending the only Catholic high school may have something to do with it... everyone pretty much knew everyone and had done so for a considerable period of time. I went to kindergarten with people that I was still good friends with in year twelve and the relationships, while developing along lines of interest, as they do, remained fairly pleasant.
That isn't to say that there wasn't a degree of bullying that took place; some kids copped a lot of shit from certain elements and no-one would ever really intrude to stop it. So, I guess in our communal acceptence that some people were given shit we were all a part of it.
