Julie did however have her legs smacked for having a dirty water splash on the back of her white socks but escaped a slippering.
Word had also got around that Mr Thomas used his slipper on a regular basis and had girls in tears a lot of the time.

That way, prefects who could give two with the slipper could not give out sashes.
