The teachers and the lessons were the best thing about school, and that wasn't great.
I can't remember any marvellous teachers, and not so long ago I was shocked by a commnet by one of my best.
My parents went to a school reunion, and some of the folk there (same school! )asked after me. One, probably my best maths teacher, told them: "In all my years of teaching, he had the most unusual mind." Why on earth did he never tell me?
Back then I was left just wondering why I didn't fit in. Not special. An ugly duckling with no prospect of becoming a swan.
