Over the last couple of months I'd got to know a guy called Robert who attends the same cardiac fitness session as me. Good guy. Fitter than me, but they all are.
On Tuesday, by chance, I heard him mention that he had worked for the same car rental company as me. Avis.
Turns out that we had worked together. Probably 40 years ago. He had seemed sort of familiar - there was something about the voice, perhaps. I had wondered if our paths had crossed in the past but then dismissed the thought.
Well we hadn't recognised one another but we do now have more than one thing in common and it's not just angina.
I wonder how many old friends and colleagues have passed by over the years and I didn't know.....
