I so get bonus points for today. A line of severe thunderstorms rolled in at 6 a.m., so that was it for sleeping, and at about 2 p.m. I hit the mental end of my workday. But then my supervisor let me know about a networking event in the city in the evening, and I went. For three and a half hours. I kept making myself stay each time the people I was talking with changed and it would have been easy to take my leave. Socializing is easier when I'm tired than it is when I'm awake, and also easier when I'm tired than mental work is, so that was all right, but still. Standing, etc. Got back and had dinner at almost 10. Sorry to those to whom I owe a comment or email.
Oh, and the other line of severe thunderstorms loomed at about 5 p.m., while I was walking to the Metro. Those bubble-wrap-looking undersides were back, interspersed with weird right angles as up- and downdrafts must have whipped the clouds' moisture around. The rounded features moved just like a pot of water at a rolling boil, only in slow motion. Never seen anything like it outside of TV.
In conclusion:
Zygote.
