I have a friend from nursery school. When ever we has lost touch, we have always come back together again through spurious links.
First time we lost touch was after we left school. A couple of years later I started work with a guy who started talking about his girlfriend. It turned out to be her.
They split up, we lost touch again until a friend from London told me that she worked with an old school friend of mine. It turned out to be her again and she was living and working in the big smoke.
Again we lost touch, then one day I was helping my cousin move into her new house. The neighbour propped around with a cake to welcome her. Surprise, surprise, it was my old school friend yet again.
We sort of lost touch again, until I one day last year I heard someone shout my name as I walked across the quad. I looked up and there she was again. She had just started a degree programme at the University.
I think fate has decided that we need to keep in touch for some reason.
