I along with three other girls and several boy was caught playing in the school’s old WW2 air raid shelters, which were strictly out of bounds.
We were marched down to the Headmistress’s office and lined up outside her door, whilst the teacher informed her of our misdeeds As there were to many of us to all get in her office, she came out and gave us a real telling-off in the corridor. Then we were taken in one at a time and given the slipper, which was in fact an elasticated plimsoll, which was commonly referred to as The Pump
We all got Three of the Best, the one concession being that we only had to lean against her desk to be punished, whereas the boys had to bend right over and touch their toes.
I remember the whole experience as being really frightening and of course painful. However afterward I can remember feeling really proud that not only had I had the Pump, but that unlike some of the others, I hadn’t cried.
