My university in the late 1960s was still divided into single sex colleges and there were still moderately tight rules intended to stop students of the opposite sex staying overnight etc. These rules relaxed very rapidly within a very few years of my graduating, but while I was there, we were still in something of a 1950s time warp.
It took me a while to find a friendship group among the seemingly self-assured, mainly private school boys in my college. And I had very little contact with girls in my first year. There were some very beautiful, chic girls around in the city, but they seemed completely unattainable. At some point early in my second year, I and a friend were invited to a party at one of the girls' colleges on the other side of the city, where we chatted up a couple of attractive girls 'freshers'. The 1960s were starting to influence even the diehard institutions of the university. Having never been inside a girls' college before, I recall being surprised to be allowed to visit the girls' study bedrooms. I don't recall what 'progress' was made on this occasion, but clearly enough for the girls to want to meet us again. Being an all-girls college, meeting anyone in trousers must have been a pretty major event. We were pushing at an open door. I suggested to the girl I fancied (I'll call her Fiona) that at the next weekend, I should collect her in my car and we could go back to my college. She leapt at the chance.
