Funnily enough the only kids I saw in tears were a few boys after they had it from the headmaster or his deputy. The dep. too was a small person, so perhaps smaller teachers could give a harder belting.
I dont remember the very last time I got the belt at school but it must have been in my third and final year, and the most strokes I got at one time was four, from that maths teacher, she was a bitch, and no I was never part of a whole class belting, the only ones of these I heard about got one stroke each, no doubt it was too strenuous for the teacher to give more. Yes I was belted at home, it only happened a couple of time and was by my mother, she had a leather trouser belt of my fathers and gave it to me on the bare bottom, very sore, but she never gave it hard enough to leave marks.
