Yes quite a few times, part of the parcel of being in a shit hole secondary school. The memory that sticks the most was of Mr.Kent or Mr.Cunt as he was so cleverly called. For no reason what so ever everyone labelled him a pedophile and some kids actually believed it and the abuse he got was unreal. I thought it was funny at first people swearing at him and generally being little shits and doing what the fuck they want and showing him no respect. But when he only wanted to help a student struggling with his work he'd get something a long the lines of "Fuck off you dirty bastard get the fuck away from me, prick."
This aint a exaggeration many people don't believe me and my mates when we tell people of the shit this teacher had to put up with. Of course he ended up quitting after people thought it was funny to report him for the pedophile shit he clearly hadn't done. The claims were unfounded but he threw in the towel don't blame the man either, I didn't partake in this, but i thought it was hysterical at the time. Makes me fee like a prick even if i was in my mid teens back then.
