I really love teaching undergraduates hard stuff. I love it. I love that I can make really difficult things make sense for them. Today, in spite of the Sickness Hangover that persists, was a great teaching day. Students rule. But really, today, I feel like I rule more than they do, because I made them think about stuff they didn't want to think about, and I explained things in ways that were clear, and I really think that they got it. Like totally.
(Of course, we'll see whether they did when it comes time for them to take tests and write papers. But seriously: I think they got what I was on about.)
