That sounds just fascinating enough to be maddening (because I'd be chafing at the sexism and the splainy and the neurotypical-normativism, but too fascinated at the linguistics to quit).

Reminds me of when my son was just starting to speak in sentences, and referred to himself as "you" for a fraught couple of weeks until he did the prism-glasses thing and figured out the linguistic convention. He'd been imitating us and, well, WE called him "you"...
