The doorbell rings and interrupts my train of thought.
When I get downstairs and open the front door I'm faced with an unshaven young man in a suit.
Salesman: "A'right mate, I'm just doin' an installation for Virgin Media for some of your neighbours"
Me: "Can't you read?" - I point to the sign on the door that says 'No cold callers'
He grinned at me.
I wasn't considering moving to Virgin Media anyway; I'm even less likely to now.
