I live in London - my cousin in West Ireland died, tragically, suddenly, and there was a rush for my sister and I to get flights, car, hotel .. Driving from the Church to the graveyard I was following another car, hoping they knew where we were going - only for them to slow and pull over, and one of the passengers to jump out and ask - in a London accent - if I knew the way. Well, both cars got there, we nodded at each other in relief at having made it to the graveyard in time but I was struck at the familiarity of the driver, a lady in her 50's.
I puzzled overnight on who or how I would know this woman in a place I've only been to once before, when it hit me. My son's Deputy Headmistress.
When he went to school the following week he struck up a conversation with her - Miss, were you in Kerry last week? She was taken aback, and said said - "how would you - Oh, Alex, was that your Mother"! She'd had the same "how do I know that lady"? Her husband is my cousins wife's Uncle.
