Three degrees?

I have written about the concept of 6 degrees of separation before . I am going to have to try and redefine what's going on for me. Last Friday I visited the North West Film Archive to do some work research. I met Will who works there for the first time or so I thought. I was taken aback when he asked me if I had been a homeopath. Turns out he started working for the college where I studied as I graduated so me and my group of fellow students were familiar names to him. Last night I went to the preview of the Dior exhibition at the Gallery of Fashion in Platt Hall. I realised that the last time I went to a preview there was when my now grown up daughter was a babe in arms. This morning I travelled into work on later train. There was a young mother with two children sitting in front of me. The little girl reminded me of my daughter. At one point I watched their bags for her and we started a conversation. She lives near where I used to live in Sheffield. She asked me if I knew a friend of hers who had lived on the same road. Her friend had been my next door neighbour. Not only did she live next door, but she and her sister were the wonderful teenage babysitters who made such a difference to our lives when we moved to Sheffield. Somewhere I may still have the note they had put through the letterbox when we arrived offering their services! It was lovely to hear about her. Some say there is no such thing as coincidence.I'm not sure.
