I am currently in that odd state in which the absence of pain is almost as distracting as the pain itself was. Also, I'm wanting not to get up and do any of the things I need to do, for fear the hadache will return when I do.
I discovered today that Acorn can use "bioluminescence" correctly in conversation; but he also said "isolation" in place of "insulation" during the same conversation. (And laughed uproariously when I pointed out the error. He could define them both, so I suspect he was unconsciously substituting a word he could pronounce more easily.)
