chance encounter

about 20 years ago I was staying in the south of France wiht my then boyfriend. we were staying with a friend called R who had moved out there, bought a wreck of a house and was doing it up. R had been there a couple of years and made some friends including some other English people who had moved to the area. it was a very rural place, quite hard to find. One night we were sitting around, drinking beer and chatting and my boyfriend told us a story about a girl he had worked wiht in London some 20 or so years earlier. I had never heard him mention her before. He had lots of colourful stories about her and we talked about her for some time. The follwoing day, R was at work and the boyfriend and I were sitting in the sun reading when a car came up the track. An English couple got out and asked for R. We explained that he was at work and asked if they wanted to stop for a drink as it was very hot. They did and we chatted. After about 10 minutes the woman and my boyfriend recognised each other. it was the woman he had been talking about the previous evening. Neither of the couple knew R, they were there because they were staying wiht someone locally who had sent them there for some reason. It was quite odd.
