Worthless day. For some reason, the books didn't arrive from the stacks, so I had only the background reading. Thick mental fog most of the day, still trying to figure out the reason. And for some reason, the folks sitting nearby were, more than once, of the non-non-creepy ilk.
Was going to stay and work at the branch library across the street, but when the mind is in an unexplained fog, best to switch coordinates. The whole reason I'm here is that I know these places rather well after 20 years. If the plane goes down, try to land in the right briar patch.
