I've been pushing too hard again. Then Secondborn woke up at about 3:30 in the morning, and apparently woke me up with him. By the time it was time to leave for work I just... crashed, hard, for most of the day. So no blogging challenge this morning -- the prompt is "things I never get tired of talking about," not "I do an awful lot of talking about being tired" -- and no writing. Just a bit of musical nostalgia instead.
