I'm sleepy. Not tired, but just sleepy. I think it's the weather. I just blew through a whole pile of work - that is, I think I did, I don't remember doing it, but the files are there on my screen done, and the odd problem from yesterday evening has vanished. Yet when I came to, or whatever, I was conscious that I'd been just staring at the screen for some time. So I must have done it a while ago. Weird. Zonked, y'know?

It is too damn warm in here, and stuffy, and my brain is turning into mush. It feels almost like I'm ill, but everyone else in the room is the same way, so I know it's not just me. I cannot concentrate worth speaking of.

Sushi tonight. And Threshold of Ages. In hopefully somewhat cooler places.
