Back when I was in third grade, attending elementary school back in the early 70s, I received the most memorable spanking ever from my principal, Mrs Smith. She was a middle-aged women who was built well and had a very strong hand.
I was sent to her office early in the school year for misbehaving in the lunchroom. She talked to me and told me what I had done was bad and not to do it again, then sent me back to class.
