Coincidences within coincidences!

In the late 1970s my friend and I went to London from the Wirral for a day out. We were in a shop on Portobello Road when I was approached by a young woman of similar age who had spotted the fish [Ichthus] symbol on the lapel of my coat. She asked me if I was a Christian and I replied that I was. She too was a Christian and had just set up a cafe near the V&A. Our conversation revealed that she had the same name (Amanda) and it transpired that she had lived as a baby in the same road (and village, obviously) as I lived. So here we were 18 or so years later in a chance meeting in the capital, 250 miles away. When I returned home I mentioned meeting Amanda to my parents. Not only did they know of her and her parents (who had lived a few houses away down the road), but it turned out that my mother had worked with Amanda's mother at Peacock's advertising firm in Liverpool in the 1950s (my mother was PA to the managing director, and Amanda's mother was a commercial artist) and my father had known Amanda's father (called Stan) from school days in the 1940s - they had been at the same secondary school (Abbotsford Road School) in Liverpool, though Stan was a older than my father and in a different class. It was by 'coincidence' that they had ended up living in the same road 'across the water' from Liverpool between ten and fifteen years later (they had lost touch once they had left school). It seemed that there were 'nested' coincidences, moving from simple coincidences (shared faith and name) to more complex coincidences within the same story. Incidentally, I heard Professor Spiegelhalter on Radio 4 citing some of the contributions to the site, including the story of the woman who had cracked open an egg to find a double yolk and later learned that a friend was expecting twins. When I put the radio on I had just come out of a dream in which I was in a cookery competition. The recipe involved separating an egg, but I failed this task and ended up with the entire egg in the bowl - there was a double yolk so I had to try and fish out the two egg yolks! I then woke up.
