I blame my lack of sleep, or perhaps my being preoccupied with a variety of other things, or the fact that I was running late... perhaps it was that I hadn't opened the curtains and the light is not all that good... okay, I made a mistake, but I sorted it out. I realised my error when I needed to go to the loo at work. I had accidentally installed my gentleman's foundation wear in reverse - by that I mean with its access channels at the rear. In other words, I had my pants on backwards. How embarrassing! If at all possible, try not to do that. It requires significant undressing to rectify and I banged my knee on the toilet-roll dispenser in a cubicle in the toilet while I sorted it out.
