I'm sorry I missed your talk in West Norwood, he says.
I didn't talk in West Norwood, I tell him.

You didn't do a presentation about the explosion of creativity amongst the unemployed?
No, I'm sorry, I didn't, I say.
So your name's not Mark then?
No, sorry, I tell him, my name isn't Mark.
He shakes his head.
Anyway, he says, I must be going. I must be moving along.
