I never saw any, either here or at any other school I attended apart from the marks of a slippering handed out to a boy of nine or so at prep school, but I saw his bottom maybe 5-10 minutes after he had been slippered and all that there was to see was some slight reddening.
Okay, I am not saying what people have written is not correct, merely that not all canings are as bad as described above.
Did others receive what we might term a “light caning” or was I unique in going to four schools where although the cane was used, there was little evidence of it afterward.
