I guess I would say that I'm selfish. I don't share anything of mine with other people, usually if I'm doing something for another person that I would not normally do, it's primarily for self-preservation.
Whenever I communicate with someone, especially someone I am comfortable with, topics of conversation usually revolve around my special interests, unless someone directly asks for my opinion on something, or asks for my help. I'm pretty big on research, and so am often finding things out for people, which again, I'm benefiting from it since I enjoy doing it. If someone asks for my help and I don't particularly feel interested in that area (such as personal issues) then I seem to autonomously disregard them.
The only thing I can say in my defence, is that I exist mostly in my own little world. Sometimes my world and the rest of civilization intercept because of direct correlation, so from my perspective it is simply an extension of my world.
I don't share the same social accuracy that my peers have, therefore I instinctively shut myself off from them since it's strange to me. Maybe it's selfishness, but either way it's not something I can help.
I definitely admit to being selfish in the most basic sense, but emotionally selfish? I think the mental restraints that a lot of people on the spectrum share can come across as selfishness or arrogance/ self importance.
