Remembering Mini-Skirts

The current discussion of 'up-skirting' has reminded me of the days of mini-skirts.

In the late 1960's I was teaching a class of FE science students, all boys aged 16 or 17. Their 'General Studies' was taught by one of the teachers of English, a young lady who wore very short skirts and, to the delight of the students used to sit on one of the desks while she taught, so after each class the lads would announce the colour of her knickers, though without mobile phones they had no corroborative photographs.
