As a neurotypical person, this is actually pretty interesting to me as well. I live in the US and here we are always taught to make eye contact when speaking to someone, as it shows as sign that you are "engaged" with that person. It's something so ingrained in you from a young age here that you start to think that this is how all humans should communicate.
Neurodivergent people just tend to ignore those social constructs, makes me wonder if we as neurotypical people play all these social games and a neurodivergent person just looks at all that as window dressing that isn't required.
