I didn't get bullied in primary school... secondary school, however, was another matter altogether.
There was one lad in my form who, for whatever reason, decided that he really didn't like me. (I was the shortest guy in the form, quiet, smart, always polite to teachers and had a weird sense of humour. Maybe that's why.) Cue years of name-calling (which, at the time, I couldn't really handle), throwing things at me (not always when the teacher's back was turned) and, whenever he got bored during breaks/lunchtime, hunting me down and beating me up, just for shits and giggles.
The worst example of this was when his friends dragged me into the football court (basically, a fenced of patch of gravel with football nets up) and watched him beat me senseless whilst they watched and cheered like it was the world's most one-sided UFC cage match or something.
Yeah... eventually, he lost interest. Funnily enough, it was around the time that we started our GCSE's, where my marks stood in complete opposition to that thing he'd told me repeatedly over the years; that I was 'worthless'...
