Someone just knocked on my door and when I opened it only a few seconds later I saw a figure already heading away from my house and halfway down the drive. He turned when he heard the door opening and said, 'Excuse me for bothering you, but is your car for sale?'
Bit of a random question, I thought, but I'll play along. 'No it's not,' I replied. 'Okay, then, thanks.' He turned around and left.
Your thoughts, please: is it possible that this particular chap was not at all interested in whether my car was for sale, but rather, were there any occupants in the house? I can't imagine too many people would be interested in buying a Y reg Ford.
