Other than dating, i have no interest in other human beings.
In my life, other than the sole exception of my desire for a girlfriend, I am absolutely indifferent to other people. I don't have friends, but I'm not a lonely person, nor am I shy or inhibited. It's more like I lack a "social drive"; I don't experience a need to "belong".
Often for purpose of work and other functional areas of life, I have to feign an interest in people and put on the impression of a more gregarious person. If I didn't have to work, I think I'd pretty much be a 24/7 hermit.
I should note that I didn't have any friends while growing up, so I've really only ever been a loner. Yet, most people in this predicament often are seriously lonely or otherwise have major emotional problems, but this seems to be absent from me.
