Meeting friends

My first coincidence happened many years ago - I was adopted at birth and didn't find out until I was 16. Two years later when I was commuting to London, I met a girl on the train who became my best friend. Sadly she died aged 31. When I was 45 I decided to search for my birth family. During my search I was given the information that my adoptive mother had been married before. I obtained my adoptive parents' marriage certificate and found the name of her previous husband - my friend's father! My friend knew, but was sworn to secrecy, and she kept that secret. I am still in touch with her mum [her dad died 10 years ago] and we often talk about this event, but my adoptive mother has never confessed. My second coincidence is also connected to my adoption. Whilst searching on the internet for relatives of my birth father I was contacted by a girl who said that she was also researching the same surname on behalf of her partner. We discovered that her partner and I were cousins - our great-grandfathers were brothers. Next she told me where they lived- just 2 miles away! I went to the gym one evening and as I put my belongings in the locker and started to walk away my mobile rang. I went back to answer it and it was the girl who had contacted me returning my call. We had never met and I was trying to arrange a meeting. Her voice seemed to echo round the gym changing room and when I asked her where she was phoning from she said "the gym". As I turned around I saw that she was sitting in a cubicle behind me! We both had to sit down then and were totally amazed at this coincidence and our first meeting was certainly memorable.
