Honestly, I think I just avoid looking at people in general. I think it took a while for me to realize I was even doing something unusual. I think I noticed when people seemed to think I should know things like "what color shirt someone was wearing". Like, why would I know? Not sure that was an autistic thing though or more of a "I don't want people observing me, so I don't do that to others" kind of thing.
How do you interpret other people’s eye contact?
If I noticed someone is making unusual amounts of eye contract, I probably laughed at them. Just seems ridiculous and they most be trying to do it as a joke.
