Alan was sick yesterday, and still is. For a few moments, I thought I got sick as well, but that didn't develop further, so I think I'm fine for now. His parents came here last night to "cheer him up." Nice parents.

I got the poset presentation outline nailed down now, so it's now a question of how to explain it as to confuse as few people in as few places as possible. Also need to wonder if my presentation is going to be too long. And need to write the slides...

What's left for the semester: poset presentation, paper, and homework; approx assignment and project; integer programming marking x 2; Bible games.
