Isn’t it just amazing how David’s internal clock resets itself by a half hour a day? I find the subject just fascinating when I am going for walks before dawn. I have recently gotten dressed, played baseball, walked to Starbuck’s, played in the park, called friends on the east coast, and window shopped for a couple miles, all before 7:00 in the morning. At 7:00, I turn David over to John and go back to sleep.
