Not a silhouette. Yesterday's frenzy, continued into today, gives an explanation for why I am not worrying about having the perfect picture for the word of the day. In a way, the spring break began today because, even though I am giving tests over the next couple days and I have homework for my second class to complete by Saturday, it's Spring Break in the sense of no teaching until the 20th. The emotional energy needed for teaching is really quite enormous, at least for me. I don't think of it that way when I'm working, but when an extended session is over, the startling peace of not having to prepare a class stands in extreme contrast to the ever-present thinking about how to explain something, about how to spend class time, about how to reach a particular student, about what aspects to emphasize etc. etc. etc. I wake up in the middle of the night planning. I plan while I walk the dog. If Lucy retained even a small fraction of what I discuss while we walk in the woods, well, she would be the most mathematically educated dog ever. In my current state of freedom I frankly can't be bothered worrying about whether a pretty picture of a few turkey tails is appropriate for the word of the day.
