Debbie Harry - even at 8/9 years old, she made me feel kinda funny, and I didn't know why!
Regarding French teachers (mistresses?) - I went to an all boys school and my French teacher taught in a mobile classroom away from the main buildings. She had the worst body odour of anyone I have ever known - the smell filled the room. She always made a point of apologising - blaming the smell on the 'classfull of sixth formers', allegedly taught immediately before my class - even though all my French classes were first thing in the morning.
Even now, when I read the number of men who had crushes on their French teachers, I can almost taste the stale, acrid scent hitting the back of my throat. Takes me right back, it does...
