The music teacher lost the plot once and locked herself in the sound-proofed recording room. And we had an English teacher who was built like a brick ****house, a former boxer. He used to invite pupils to do what they could to hurt his hands, whether it involved stamping, stabbing with a compass etc. Turned out he was gay. We should've known really, on our leaver's holiday he took a 'friend' with him but nobody cottoned on.
