Overall I have a preference for being alone. Having other people around often bothers me, in particular if I have to share my time between paying attention to them and pursuing other (lonely) activities which I'd rather do instead.

However, I also can't feel happy without at least some human presence/interaction. I know if I stay alone with no contact at all for more than a few days, I'll feel lonely and start craving some human company. The way I balance these two impulses in practice, is to live with the same person who I get along with well, almost 24 hours a day, day after day, and have otherwise very few other contacts with other people. This is in no way perfect, but it's better than any alternative I can think of.

Overall, I tend to dislike interacting with/within groups of people more than with individuals. I particularly enjoy discussing interesting topics, so long as it's just with one person. I'm often disappointed in people, have fairly high standards, and only a few topics of interest which I like to share. This severely limits the amount of people, and circumstances in which I can pleasantly interact with them. I can still interact with just about anybody, I just don't enjoy the perpetual strain I experience when doing so.
