My teachers loved me - always a goody goody. Remember a boy sitting next to me who was asked to open his fist. The teacher had a scale and hit hard on his palms - at the same time his knickers came down. I noticed his shoelaces were open too. At that time I thought it was the impact of hitting him. He gave out such a loud howl, the class never dared to raise voice in that teacher's class.
Times are different now. Teachers have to be very tactful.
