Because of the schedule of meetings and Gretchen needing to go in for a follow up appointment for her eye surgery, I had an early and not too large lunch. The net result of this was that I hit the wall at about 4:30.
The nice thing about working at home is that the commute to my bed is short. A half-hour of not-quite nap and I felt much better and was able to get some more things done.
With luck, tomorrow will be less disrupted.
