You must understand, yesterday was spring: blue skies, sun, high over 10C (50F), ice melting in rivers and gurgling down street drains. For twenty whole minutes my knees didn't hurt and I walked quickly to work, wishing my bike's brakes weren't so unreliable so I could bicycle as the day demanded. Yes, well. It snowed all through today, heavily, with a bitter north wind and temperatures falling; I cleared paths at work three times through a good 12" accumulation. The main drag's sidewalks were plowed, I think: but I looked at the flat trodden snow as I walked home and said 'that's going to be ice by tomorrow.' And indeed, clearing my own street, wherever the snow had been trampled down, it had gone to an unmoving kind of half-ice. March snow is always an odd unchancy beast.
Upshot of insomnia, season change, weather change, and 8:30 to 5 day is that I've sort of misplaced myself tonight, and very pleasant that is. Must be awake to greet dryer cleaners at 9 tomorrow, but that means sleeping in till 8:30. Which this week is a luxury.
