Well, Laurie's problem seems to have been a more-or-less passing dizziness spell brought on possibly by heat, stress, lack of sleep, or all of the above. (Part of my brain is trying to imagine her in a Southern Belle costume saying "Ah feel fayint!" but the rest of my brain ain't having none of it.)
Anyway, she's feeling much better now (hooray!) and we've gone in to work (le sigh!).
