They are not in charge. It’s just that autistic people sometimes take non-critically not even what they are told, but the situation and the emotion as something normal, because that other person is more social and knows how it is.
The rules are different for every tone, discourse, context, etc. Adjusting for one of them won’t do much good even.
You won’tever lift the weight of adjusting yourself for such expectations well enough. Putting more trust in your own perception of what’s rude and what isn’t is the only way to deal with it.
I mean, probably a therapist would say that. Still ask your therapist and not Lemmy.
