I did see a girl cry once , but when she got a detention, I don’t think she ever got CP.
On red faces, a couple of years ago at work, two women were given a severe telling off for coming back , very late, from lunch and missing a meeting.This was in public and both ladies went bright red. One of them was in her late twenties and a mother of two, the other much younger. I was really turned on as it reminded me of schooldays though obviously they were not slippered !
The barmaid I mentioned has still not had a smack from me, she had a rather unappealing denim skirt on the other day, but she does wear tight jeans and even better , a pair of very tight black trousers, I will bide my time.
