Several years ago, we were invited next door to meet Claire's new classroom assistant, Jonny. Claire is a music teacher and I was just getting back into making music, so there was some common ground.
The conversation got round to people's backgrounds, and Jonny mentioned that he was from Pembrokeshire. That's interesting, I said, we've just got back from there, know it well, what part?
"Well, I'm from a little village in the south, called Amroth," said Jonny.
"Really? Just along from Wisemans Bridge? That's where the caravan is. And I used to go there on family holidays as a child, fifty years ago. We stayed in a house called Maida Vale, just up the hill from Wisemans. The family was called Richards. I used to play with their middle son, David."
Jonny stared at me.
"He's my uncle," he said.
