Fifty years ago getting slapped as a little kid was all part of the learning experience.
The teacher in our first class just used to slap us on our hands but not very often and not very hard.
But the teacher in the second class, Mrs White, used to slap as hard as she could on the tops of your thighs.
She pulled up the girls skirts and boys shorts and gave 2 to 4 slaps on the sides and backs of your bare legs.
I think it was probably worse for the girls because it was easier for her to reach that really sensitive area just below the knickers. But, boy or girl, she was usually able too make the kid cry.
How I hated her.
