if not sociopath, perhaps one of those autism-variants. the kind that makes you functional, but not quite relatable with the rest of humanity.
I have a sociopath on my team and used to have another guy with a different thing where he couldn't look people in the eye or easily talk to people, but he could focus on technical details (he had a real thing, i can't remember what its called, something-berger's I think).
As I can't name what you have, obviously I'm not qualified to diagnose you. But you are exhibiting traits of some kind of social issue. I hesitate to call it a problem or disorder, but I suspect there's a name for it.
Assuming you do have a Thing, if it's not causing you problems, I wouldn't worry about it. Just be aware that it may cause you to look at things in ways that make other people look at you funny. My sociopath only seems to hurt bike couriers because there's a legal vector for it, otherwise, he's mostly safe.
