This truncation of the world induces a low-grade claustrophobia, but the consequent anxiety is soon displaced by ennui generated by heat exhaustion. It's consequences today were no surprise. After dragging myself around Safeway and Kmart for a while, I returned home only to fall asleep on the couch. I didn't wake up until nightfall, and the windows thus remained closed long after the outside air had begun to cool off. Now the house will be hotter than it ought to have been all night, and my sluggishness will last longer.
On the bright side, I have new socks and a ream of cheap paper from Kmart. I don't know that they and a few supermarket comestibles were worth going out into that heat, but it's over now. I'm just glad it's night now and I can get a breath of cool air.
