Cross-border coincidence

Several years ago I lived and worked in Zambia, having lived in the UK my entire life before that. While I was there I briefly worked on a magazine with a Zambian woman who had never lived or worked in the UK. </p> <p>Three or so years after I returned to the UK I arranged to meet a friend in a cafe in London. I had never been to the cafe before though it was close to my office. While there I realised that I recognised someone. It turned out to be my old colleague and friend from Zambia. She had - unbeknownst to me - moved to the UK to complete her Masters. Nothing strange about that but she had also never been to the cafe before and it was several miles from where she normally lived and worked - she was taking a break from a one-off seminar taking place in a building nearby. </p> <p>That was pretty strange in itself but as we got talking we realised that, not only had we coincidentally met in the cafe, but that she was now living in a flat no more than five minutes walk from my house in another part of London close to where she was completing her degree.
