L woke me up this morning to announce that banks are closed today. L is five. Somehow, this important fact is of pressing importance. She asked me if there were holidays when the dinosaurs roamed the earth. I explained that there were no holidays because dinosaurs didn't have days of the week or months. In fact, they didn't keep track of time. They were as unaffected by bank holidays as a five-year-old is today.
Why do we keep track of time? If I remember my Daniel Boorstin correctly, it's to guide our productivity and to give us all the illusion of accomplishment even when the task at hand is not quite finished. That certainly describes the way I'm spending my Veteran's Day: grading an infinite pile of notebook paper reminiscent of this Ig Nobel scientific experiment.
