Joelle visits Gately: moo or mew
Gately makes his chest go up and down rapidly to signify amusement. He declines either to moo or mew at her, out of embarrassment.
Context
Sincerity conducted past a disabled irony-organ. With a tube down his throat Gately can only mew, grunt, hike eyebrows, heave his chest — and the incapacity strips out the option of verbal irony entirely, forcing all his communication into pure single-entendre gesture: a chest-heave for amusement, an eyebrow-hike to make her smile, a hand laid on her wrist to ask her to write. He can't hedge, can't deflect, can't wrap anything in tone; the body that can't speak also can't be ironic, and what's left is naked signal. The register war won by default when the irony-organ is out of order — while Joelle, still able, keeps her own residual distance with "a mental thumb to pretend to look at while she talks," the intellectualish arm's-length Gately's tube has made impossible for him.
