Violent teachers

Hello,
I am posting today from an Apple Mac. So what!
I am in work. There is a book in my office that dates from 1961. It is called "Ordinary Level Mathematics, with answers".
It is the "with answers" part that reminded me of something.
When I went to school it was still generally accepted that teachers could maintain discipline by using physical violence.
Some chose not to, some seemed not to need to. But some of them seemed to positively relish it.
One day in Maths class we were doing an exercise from a text book, which, like the one I have just described, had answers in the back.
I can't remember exactly the wording of the question, but it had something to do with multiplying a number by "the number of pages in this book". So I turned to the back of the book to look at the final page number. The teacher saw me doing this and he picked me up violently by the ear and said," Looking up the answers in the back of the book, are we?"
Rather than allow me to explain, he just lifted me up higher, so that I had to stand on my chair, and then he just humiliated me in front of the whole class.
