Last weekend, I went with Jeff and his extended family to his cousin's graduation in Swarthmore, Pennsylvania. We spent a couple days going to graduation events and graduation meals with the whole family. It was nice to see everybody, and congratulate Dan.
Monday was Jeff's first day of class... as the teacher. He's been a TA before, but this is the first class where he's in charge of everything: the syllabus, all the lectures, the grading, etc. I decided to audit his class, both to learn about Game Theory (that's what he's teaching) and to support him and give him feedback on his teaching. It's been really fun - though I have a pset due on Monday. :)
