All his primate-brain mapmaking machinery is worthless in these dimensions, but Salvador likes to feel it trying. Teasing it, he turns four right angles and still ends up orthogonal. His brain struggles like a beetle on its back.

There are physical laws here, of course, like the conservation of characters. Salvador nods to the only old man in the world, from whom he’s asked directions nine times.

“Howdy,” says the old man, “nice to meetcher, sentientlike construct.”

“Sentientlike?” retorts Salvador.

“Sorry!” The old man guffaws. “Didn’t realize you took the Turing test… and passed!”

Seriously, in that dimension it’s hilarious.
