A few teachers told you to report to them for the slipper at break, but would let you off when the time came with a telling off, while others would have touch your toes for 1 to 3 whacks depending on the teacher.
Detention night was on a Friday and it held a detention slippering on the last break for any boys who had chosen that ant the teacher had not slippered at the time and for any boy who changed his mind about doing detention it 2 whacks for a 1st former up to 4 whacks for a 3rd former done over school trousers, it was done so hard that most boys cried or were very close to crying.
