We were up until 2am and change, visiting with lyssabard and tlttlotd, and then up at 8 to see them off on their return trek to the DC area. Ferrett managed to go back to sleep for a while, but I just kept skipping on the surface of sleep.
Now I'm at that "too tired to really do anything but feel like I should" phase. Sort of restless, but without the energy to actually accomplish anything. Maybe a nap would help. If I can manage to fall asleep.
