That's an interesting question. There are lots of folk in my life that are fun to spend time with - to play with, to toy with, to keep score with, and to use and destroy if they deserve (or actually, if I want to, let's be honest). But I also like very much to be alone.
I can "turn off" the full on sociopath stare to a degree and "play nice" if I want to do the 'normal' friend stuff, but I almost always realise half way through the evening that I really couldn't give less of a fuck about these fucking people.
I don't really do 'lonely'. At least, I don't ever feel lonely enough to think "ooooh, what I really need right now is a friend to talk to and share my feelings with." I sometimes think that I could be having more fun if I had a few potential playthings about me, but that is a wholly different thing. There's always a place to find a plaything somewhere or other, so I don't stay "lonely" like that for long.
My main problem with socialising generally is that I don't seem to be able to distinguish between what people think is 'normal' small talk, and what is really too much information to be sharing with a short acquaintance. I find myself more and more concentrating on NOT talking about me - just keep it on them. But then I know that I get all over interested, excited, and I delve too deep for a first meeting - they find themselves telling me that they don't have orgasms with their husband, or they once slapped their two year old in the face. That's not 'normal' either - people overshare, then scare themselves and back away as though they can see me feeding on their deep, dark, dirty secrets. It feels as though I want to lick the tears from their face. I feel it, they feel it, there's a shared moment that could not have less to do with empathy, then they pull away from me. I have to avoid doing that if I want to make or keep "friends."
I was once trying to make small talk with a girl, with the vague intention of fucking her later if I could be bothered. She asked me whether I wanted to fuck her, or to eat her, because of the way I was looking at her. I carried on staring straight in her face and said "I'm just trying to decide which one I want to do first." I thought it was quite a sweet line, and it did work (poss the confidence/ eye contact?) but she left very quickly the next morning and told her friends I was a "predator" and to stay away from me. The surprising upshot of all this was that I got laid more, rather than less.
I guess that's the sum total of my small talk - and the definition of my problem with 'friends.' They bore me, I frighten them, or use them too much for them to stand it, or delve too deep for their comfort, or I'm too supremely unbothered about them (unless it suits me to be otherwise), or I end up fucking them because they like the full on sociopath stare.
I have tried, but I simply can't fake normal small talk. And in fact, I really can't be arsed with it either. If I were to fake it effectively, I'm absolutely certain it would bore me to tears. I really could not give less of a fuck about where you went on holiday, what your daughter's exam results are, or what you think about the changeable weather. People say these things and I stand there and all I can hear is "blah, blah, blah" whilst I imagine how many ways there are to gut them using only the objects in the room and what their blood would look like on the carpet. Fucking small talk.
There's a guy at my work. I'm 99% certain that he's a sociopath - at least, he absolutely relishes the high risk, dirty tactics points scoring game that we are playing with each other's credibility and reputation. Even when I crush him like a worm (which I do often - but not so often that it gets dull) you can see him rolling it around his mouth and it coming up in a hard little "I'll get you next time" smile. Great fun. Something like having a tiger and keeping it in the living room - fun to play with, keeps things interesting, nice to look at, but you don't want to take your eye of it for too long, and you probably want to lock your bedroom door. But I don't think that's "friendship."
I honestly wouldn't know what to do with a "true friend" if I got one. Fuck with them, probably.
