Hi I never had the pleasure of the Coombes family teaching me chemistry but a male teacher whose name I forget but who took unkindly to me sitting out a chemistry lesson ( literally as I decided to sit in the boys toilet for the lesson-could never get the hang of chemistry ) My hideout was discovered, I returned to the lesson after which I was told to wait after class and the said teacher with a gleam in his eye detached the rubber bunsen burner tube and delivered 6 of the best- I'm sure the Coombes could never top that.
