Since the world began, there have been only a handful of cases where it is reliably established that a girl in Britain was punished on the bare bum by a male teacher or headmaster – and every one resulted in the man facing criminal charges.
Those few cases aside, there appear to be NO cases where it is reliably established that any schoolgirl in Britain had her skirt raised for punishment by a male.
Indeed, the number of cases where it is claimed that a girl in Britain was whacked ON her skirt by a male are very few and far between.
I think we may safely say it’s extremely unlikely that your history teacher was whacked by a Headmaster for smoking as a fifth-former.
