One person, two coincidental meetings

In the very early 80s I was British Council programme officer for a Bulgarian violinist studying in London on a scholarship and got to know her fairly well, but we more or less fell out of touch when she returned home. About three years later, in about 1985, I went for a walk one Sunday afternoon on Hampstead Heath with a friend who was staying with me, something I almost never did, even though I lived not very far from the Heath, having moved from another part of London since my Bulgarian friend had left. When on the Heath, for no particular reason other than curiosity, I made a point of diverting about 30 yards off our path to go and look at a notice board. Imagine my surprise to see advertised a violin recital at Kenwood House that very evening with my Bulgarian friend playing. Naturally I went to the concert and I think she was as surprised to see me afterwards as I had been to see the concert notice in the first place. It turned out that she had tried to contact me by phone at my old address but had not managed to get my new number. Again we did not really keep in close touch but a few years later I was working for the Council in Prague. One morning in mid-1989 I was about to fly from there to Paris with my wife to visit her parents who lived in southern France. Imagine again my surprise to bump once again into my Bulgarian friend at the airport, This time she was changing planes in Prague to go on to Sofia, returning from doing concerts in Mexico.
