I'd been taken along to a fancy "do" in town, invitations only kind of thing. My mate went to greet some people he knew, introduced me, then went off to the loo. I was left trying to make conversation....which I'm not very good at. Got talking to a very stand-offish man in his 40's, and went "So, what do you do?". I was met by embarrassed silence all around...
Not only he was the organiser of the party, but he was something like THE most famous radio man in the country, famous music producer and all....
Well, how was I meant to know??
