This is kind of a no-brainer, but it's a revelation to me, here and now: It's pretty hard to play "lost in a trackless desert with a dry canteen" while you're bailing water off the floor with a sponge mop.
Probably prompted by the first grade teacher who responded to one of her 40+ charges' request for a drink of water to "pretend you're lost in a desert"… (She's also the one who bawled me out for not telling her I had a nose bleed. I was in the reading circle and skipped a word I could not see. WHY? It had a large drop of blood on it from my nose.)
