It seems to have been geological ages since I've posted anything - call it pressures of work or arrant laziness - but I saw something that got me thinking, this morning.

On the way from the station to the office, I regularly pass the London headquarters of the Travolta Cruise Institute for Fraud and Lying. I did so again, this morning, and saw a lorry parked out the front, apparently delivering new windows. They were quite large - perhaps 10' x 5' and were tinted a slight bluish shade. It's this last that surprised me; I assumed they'd be clear . . .  >:-)
