Ah yes, the Science teacher! Has had a very extensive education, knows and updates everyone about many interesting topics in the world of Science, and enjoys gourmet dinners with fine wine.
Actually I had a Physics teacher who was a rampant misogynist and despised his female pupils, a Chemistry teacher who also taught rugby (ferocious chap) plus a really lovely Biology teacher who knew how to teach with enthusiasm and insight. Thanks to them all I passed with Grade 1 in all three subjects.
My favourite though was a very camp, gay English teacher, Mr Shearn. He read out to us all the poems and quoted Shakespeare with feeling. He acted out the parts as if he was on stage. I was fascinated by him and got an 'A' at A level thanks to his dedication.
It takes all sorts eh? (innit?)
