He was our English teacher, but the only lesson I can remember was "how to perform a parachute jump". Standing on his desk, he spread out his billowing black gown to simulate a parachute, then leapt off, to land on the floor in the correct attitude, feet-together, collapsing and rolling across the floor to absorb the impact.
Then each of us had to execute a jump from the desk to see if we'd been paying attention.

At top left is Lex, who would much later be the reluctant witness of a belting I received. Top right is Colin, a dear friend still.
Once again, I'm sitting beside the teacher, just like in the happiest days. Coincidence?
