A word about communication differences in autistic folks.
Non-autistic people: That confusion, frustration, surprise at sudden unexpected turns, and impatience that you experience constantly when listening to an autistic person about an important matter? Yeah, we feel *exactly* the same way about what you're saying, for *exactly* the same reasons. Only for us, we have to deal with that in almost every single person we meet, not just one. It's so pervasive and familiar to us that we invented a term for it, now confirmed by supporting research: the double empathy problem.
So before you cut one of us off or otherwise stop listening, please take a minute to consider what it's like to live on the business end of that negative behavior you're about to display. Imagine putting up with that from the majority of people you interact with. And maybe try to listen a little more attentively. Because whether people listen or not, we do have things we need to say.
