I met one girl when I was 9 and she was the only person in my class that could make full eye contact with. I never really understood why, but I became great friends with her and we still talk to each other every now and then. Later I learned why I could look at her so well:
I met her sister. She was 3 years older than me and fairly reserved. She barely glanced at me when we talked and I could make complete eye contact with her too, but not their mother. I later learned from her sister that she was diagnosed with Aspergers, so I'm not quite sure how I knew that.
With autistics or siblings to autistics (including my own) I felt I could better make eye contact and overall communicate well with. I don't know, but my brain wraps around that little notion frequently. There are some NTs I can make eye contact with, but not as many compared to those of the aforementioned category.
