YSP Day 7: Least Upper Bound

I keep titling my posts with what we learned, but I don't remember much of anything today. Today was special for reasons unspecified, but even without the cooling sun and thai pad noodles and even with my failing calves and softening quads, it was comfortable. Sleepy, tired, and very comfortable.

Here are some portraits I drew today.
(Left) This quiet white kid never moves. He's one of the few people who has already taken an analysis class, so he's pretty great at everything.
(Middle) Professor Sally. Apparently he's also the administrator of the program. And yes, he really does look like that when he talks. Its a side effect of getting old.
(Right) The back of Matilda's head.
