Of course, the most unforgettable classmate I had was also the most vicious bully. I attended a boarding school for badly behaved children and it had its fair share of bullies who had been expelled from mainstream schools. But this particular bully had even the teachers running scared. When he went off on one, it could take up to four teachers or members of care staff to get him under control. On my first night at boarding school, he stamped on someone's face and left them permanently disfigured. I never saw anything that bad again but it stayed with me and I could never sleep properly in that school again. On another occasion, it blew up and there were several members of staff restraining him when he farted. To see the teachers all moaning and groaning and huffing and puffing whilst trying to hold him down was hilarious, literally tears in their eyes. He was unpredictable and he didn't care. I once saw him swing a hammer at another pupil and throw snooker balls at another, and he used to punch as if he was throwing something, so it would result in a painful blow. Eventually, the staff couldn't cope with him as they were just as scared as we were. He was removed from the school and placed in a secure unit. The night he left, several of us cried with relief. Last year, I was reading an article in a newspaper when a name caught my eye. It seems he became a hopeless heroin addict at some point and had died in his flat on an overdose of prescription drugs and smack. I felt sad when I read it but I couldn't work out why. Maybe it was because my brother died in the same manner? He was certainly a character, an absolute nutter and ruthless bully who had everyone fearing him. Most definitely the most unforgettable classmate.
