I used the time waiting profitably. I say that, what I actually did was configure the little iPaq I use for my sat nav so that it could access the internet via my mobile phone. I've tried such a thing before, but it didn't work and I really don't need it to. At the moment, though, I'm working all day on windows portable software and so I'm much more familiar with the operating system and experimenting with it. So, I got it to work. Then the battery ran out. I know it was pointless. Curiously, though, I think I may be suffering from some work-related phenomenon where I can't actually unwind and stop doing stuff. So, I think I just had to work on something while I waited for my friend to arrive at his house, back from his week away in Wales. (Week away in Wales - sounds Welsh just to say it, doesn't it!?)
We prepared for the DIY. We did this by playing his new piano a little. Then we prepared further by buying a car load of materials. Then we prepared by buying some "Benefit Flakes" from Aldi - an apparently joke-named item that proved to really exist and taste ok.
Back at the house we got going on the DIY which proved to be more work than we anticipated, and also took us to midnight. There would be much work to continue the following day.
