I met a female friend in Bristol thanks to another mutual friend. Chatting, it turned out she studied Geology in Liverpool, so did I but I assumed she may have gone to the University whereas I was at the Polytechnic (1980's). She said it was the polytechnic which had several sites, so I enquired which one....it was the same site and she was there at the same time, although in the year above me. Probably went on the same field trips but I don't remember her. What are the chances of running into someone who went to the same college at the same time, studied the same subject and over a decade later you run into them?.
