But it's 8:20. It seems very strange to be out of bed bright and early, typing at a computer over half an hour before I would normally be awake enough to do so, for the purpose of announcing that I'm ill. You'd have thought I ought to stay in bed until about ten before feeling ready to even bother to call my boss.

Nonetheless, my sleep patterns are disrupted, my brain isn't working straight, I can't type fast or accurately, and if I sit at this computer for about another ten minutes I will end up staring blankly at the screen and doing nothing. Therefore I'm ill. So I'll mail the boss and then go and go ug on the sofa or something :-/
