I was at Trinity from 1969 to 1974 and can clearly remember Mr Casey, he was a lovely bloke but far too soft to be a teacher!
He had to put up with the usual juvenile pranks which seemed hilarious at the time, matches slipped into hollowed out chalk etc. I can recall one particular day when, at the end of one lesson, we were all rushing down the stairs of the tower block when someone who will remain nameless (you know who you are!!) decided it would be great fun to push Mr Casey from behind! Down he went, landing in a heap and banging his head on the wall. As a 14 or 15 year old it was funny at the time but in hindsight obviously it was so stupid!! I hope he's still around and in good health, does anyone know?
