My grad students did half hour presentations today, completing the teaching term. While I always enjoy teaching and had great students at all levels this semester, I think the combination of a large number of classes and the admin duties overwhelmed me. I've been more tired on a more continuous basis than I ever remember being. The weather didn't help, nor did the many colds running through the house. It felt pretty good to buy a round at the Owl for them after the session was done.
