You may wish to have more details of the girl who was given the detention by my maths teacher. She was one of the worst behaved girls in my year and I strongly suspect she may have received a slippering if not the cane. She was often sent out of the door and had numerous detentions.
The teacher who I still see told me a couple of years ago , over a liquid lunch, that her parents gave him more grief than any other parents in his entire teaching career.They used to phone him , write to him, and turn up at the school over some perceived miscarriage of justice that had happened to her.
