keeping your eyelids open by means of match-sticks

In the school in Watford. Have been here nearly two hours and still no pupil in sight and a couple of warnings about others not going to be around. Falling asleep, too: didn't get much sleep last night. For a while tried to practise guitar -or, rather, read the Chaconne by Bach, which I haven't played in about 20 years, and discovering that I still remember many of the things I did in that piece but in many cases I no longer like what I used to do so I would have to rethink how to play them.

If only there was a quiet corner where I could close my eyes for ten minutes...
