Girl P was never given the slipper or cane herself , but as one of her duties as Head Girl, she once had to escort two girls to the Headmistress’s office for a caning. She didn’t actually witness the caning but had to take them to the sick bay afterwards for a recovery period, before returning them to the classroom. I have no idea who these girls were, but they would have been about three years younger than me.
I would have loved to have asked for more details of girls being slippered, but I think I went as far as I could.
