So one mystery is solved--my wayward roommate has returned--apparently he has been harassed by an organ of Dick Cheney's America for some time now--something straight out of Kafka. So it's hard to ask for rent under such circumstances, and it's all rather scary, as surely this here blog is at least a little politically heterodox, and no doubt vaguely monitored.

Today's exercise at teaching another teacher's class an overprepped lesson was instructive: I sweat too much, and there are good, sharp math people out there--who would have thought that fruitful cooperation could be possible? So I am pleased, and actually energized yet again--it's been two good teaching days in a row, though, granted, I only taught for 50 minutes today, so perhaps that's a good teaching day by definition.
