Where'd the day go?

Huh. It's 4 o'clock and I haven't been outside yet. I had today off to prepare a course that I'm running next week. I managed to get 2 hours of solid wokr done in the morning, which was great. But now it's all 4 o'clocky and I haven't really done anything with the afternoon. I guess I'll be doing some work in the weekend. Now I have a whole bunch of chapter summaries to write. I may in fact have to go into work to pick up the book. I've been greatly enjoying reading people's blogs. I suspect that maybe that's where the afternoon went!
