Folks, I was up most of the night with Anand, who was up every hour or so all night. (He seems to be done with the throwing up now, but still feverish, so he's staying home today; Kevin isn't teaching today, luckily.) I'm feeling okay now, but groggy; my plan is to go in, teach my classes, come home and crash. So if I owe you e-mail or other work, just figure it's probably not getting done today. Sorry.
