Are there many Bullies?

So maybe I have just been lucky and have lived a charmed life.. but in my experience in primary and secondary school, most of the whole class/year got along well except for the odd person with whom You’d still be civilised with..

Is there much experience in Ireland of serious Bullies? I know American TV shows depict a lot of high school bullies, so I’m curious are there as many as we see on TV?
