there’s a couple of us who talk occasionally about trying to map out some of the basics of what certain things mean, like body language signals and common phrases/questions. like a phrase book for aspies.
we’d probably need allistic people to review it for us, though. and most people react badly when you imply that things they say mean something different or additional to the literal translation.
there’s a reason that when you’re studying another language you’re only given ‘I’m fine’ as the stock answer. and that so often when people answer with a negative it’s with a jovial tone, and will wait to be prompted before explaining.
