You've got to be careful in hotels. They put mirrors all over the place. There are a whole bunch in the bathroom, which in my opinion (and my condition) is a really bad place to put a mirror. They also have them on the lift doors. I was alone in the lift travelling down to the lobby and, staring at my reflection, thought I'd have a go at gurning to pass the time. As you do.
I just managed to pull a truly deformed face (not, admittedly much of a stretch for me) when of course the doors slid open to reveal a rather well dressed couple who were on their way out to some posh do or other. They managed not to actually recoil at the sight of me, but they did seem slightly worried as they got into the lift and the three of us made it the rest of the way down in rather stony silence. Oh well.
