I have this vague theory that if I can avoid looking at the clock as I get into bed my body won't know it hasn't had enough sleep next time I see the clock. But it's hopeless if I have to get up early (as I did this morning), because I never trust the alarm to wake me.

Rosie came up with a very helpful manoeuvre last night, whereby she sat on the end of the bed until I got into it and switched off the light, whereupon she headed up the bed in search of strokes, leaving a nice warm spot where my feet were about to go.
