Okay, that turned into a 2-hour lunch break 'cause I ended up spending 40 [rather than the estimated 20] minutes at the glasses place (the frames have needed adjusting for a while -- they slide down my nose, plus I'm lopsided -- and the guy was a bit of a perfectionist) and I stopped to get a Harvard T Station smoothie on my way back. I passed Prof.B. [who had been at a 3½ hour meeting] on my way in, though, so it's not like I was missed. (And it's not like I've had much to do since. My job makes me tired sometimes -- the waiting around for Prof.B. to get me the info I want.)
It should have felt worse when I left for lunch than it did in the morning ('cause obviously the temperature was higher), but it actually felt better. Maybe the air was drier?
I'd forgotten about the predicted thunderstorms until I was walking back and heard thunder (and saw dark clouds). Nice.
I never did eat my lunch today. Oh well. (Another hour and a half left? Sigh.)
