I just prefer my own company, man. Think it’s part an ego thing, part defence mechanism. Don’t think most of the things i enjoy most are improved by the company of other people - reading, watching films, eating, sleeping, getting pissed, listening to music, watching sport.
The thing is balancing that with having just the right amount of company that you get to share your thoughts on all of those things, and widen your exposure to stuff on other peoples recommendations, and keeping your mind socially active enough that you’re vaguely comfortable around people. I do none of these things.
When i do go out i just much prefer the company of one person. I like the silences, the “yeah but, how are you…?” conversations, the reminiscing. As soon as there’s a third person i find it a bit dizzying and impersonal.
