Cycles

OK, what's going on?

Monday I felt completely flat - not enough sleep, even with an afternoon siesta; uninspired - thank god we're near the end of the year; and not inclined to be more than minimally civil to anyone.

Tuesday I had a long lovely lie in, so relaxing, and my students accuse me of being hyperactive (not that they used that word, more like crazy waving hand gestures). Of course by the end of the day all I want to do is sleep again and I'm still feeling quite anti-social.

Tomorrow - who knows.

The only thing I do know is that I really don't want to make any effort at all. I would expect this to happen over the course of a month, not over a couple of days.

Must check my biorhythms.
