Not a relationship, but an interesting sequence of events.

A few years ago now, I used to commute into Bristol daily by train, and often there was a blind man with his guide dog making the same journey. We regular passengers used to help him and his dog climb aboard, and alight, as appropriate. Indeed, on one occasion (I have recounted this story before), the guide dog toppled off the platform while trying to avoid walking through puddles at Nailsea & Backwell - and several of us rushed over to retrieve her from the tracks.
Years later, in my current job, I now deliver groceries to that man - and I introduced myself, on the first occasion, by referring to that incident. The blind man was delighted to renew our acquaintance - "Blimey, Chris, I haven't seen you for ages!" he said.
