Co-incidence on a pontoon in the Indian Ocean

I live in Notting Hill and I work in Central London in film and television. A few years ago, I was in a meeting at my office with a film producer, who I knew, and his colleague, a young girl who I had never met before. Their offices happen to be in Notting Hill. A week later I went on holiday to my favourite hotel in Mauritius, 6000 miles away from London. It's a very private hotel and in general the guests keep themselves to themselves. The day after I arrived I swam out to a pontoon that the hotel has tethered in the ocean off the hotel beach. It's wonderful because it is not only one of the most beautiful spots in the world, but it is not often used by the guests. I was the only person on the pontoon, but shortly after I had got onto it, I was joined by a man and we got talking. He was English but lived in Amsterdam and was a dealer in Dutch Old Masters. He asked me where I lived. I told him Notting Hill. He asked me if I knew a particular road in Notting Hill. I said, yes I knew it well. He told me his daughter worked there. Yes, you've guessed it - the girl in the meeting was his daughter.
