Dogs and early mornings:

OK, so it wasn't technically very early, but Smoky woke me up about 10:00 this morning when he came upstairs and barked at my door. He was apparently hungry. Because, you know, doing nothing all night is hungry work. As is doing nothing all day.

He wasn't going to shut up until I got out of bed, so I got up, let him out and fed him, and tried to go back to sleep. But it was too late. I was irretrievably awake. I tried for half an hour or so, lay curled up on my side and wished I could sleep, but I couldn't.

I haven't been able to sleep well for about the past week anyway. I almost fell asleep at work twice. But when I go home and go to bed, it's like there's a wall between me and sleep, and I can't get through. I'm supposed to be catching up on my sleep this summer. Why isn't it working?
