Autism: Eye contact avoidance.
One of those things neurotypical people make a big deal about– eye contact! It’s really uncomfortable for a lot of autistic people to look people in the eye. This video goes into why.
I put on mirrored sunglasses to demonstrate how I “read” people by making you “read” me the way I “read” you. Rather than focus on eyes, I look at the moving part– mouths! I guess at emotions by a person’s general body language, tone of voice, what their eyebrows are doing and the presence or absence of a smile.
Neurotypical body language is unique like autistic peoples’ body language. Some autistic people flap when in distress and others flap when they’re happy. So one NT might bite their knuckle when they’re upset or distressed while another does it because they think something is hilarious. It’s all about knowing what’s what for that individual person.
