Rolling Stones..three totally random meetings

Back in 1966 I was walking down Carnaby Street together with my mother. A girl in a topless dress came the other way ( the only one I have ever seen ) to the cheers and whistles of a crew installing underground telephone wires.On the next corner Charlie Watts of the Rolling Stones was just standing around, looking very much the worse for wear.About six years later I was at Heathrow preparing for my flight to Vienna,Charlie Watts ended up sitting in the seat in front of me.About 6 years later I pulled up at the port in Ostende after a terrible drive through thick fog. Mine was the only private car waiting to board the early morning ferry until a huge US style estate car pulled up behind me.Low and behold Charlie Watts got out,together with the rest of the Stones apart from Mick Jagger.I bought a tea and a sandwich once on board and sat in the cafeteria.The Rolling Stones came in bought some teas and snacks and sat down just behind me.It was then that I considered how strange it is to " bump " into the same person completely randomly on three separate ocassions.Perhaps there is a way of working out the chances of that happening.Perhaps it happens more often than one thinks. I would have been unaware of the chance meetings had it not been a famous person. How many times do you actually bump into " Joe Bloggs " in your lifetime.....
