Have you ever had that feeling when something is not quite right but you can't put your finger on it?
After a long multi-segment journey I was relieved to be driving home from the airport and was looking forward to unwinding chez Wilco. The light bulb did not go off until I discovered that my key would not open the front door - and then it took me a moment or two to figure it out.
No, Mrs Wilco had not changed the locks. We had moved house the previous year! I must have really liked the old place. Fortunately it was only a few miles away.
