I'm a bit of a misanthrope, and quite often fantasise about "Omega Man"/Post-apocalyptic/Zombie survival settings where I'm either the last person left alive, or alone apart from small pockets of survivors here and there.
I like company on my terms, but that amounts to socialising perhaps once per week and then 4-5 days where I don't see another soul. I'm not introverted, quite the opposite, I just don't crave company and I have no interest in pointless chit-chat. I deliberately do not live with my partner because we know we'd drive each other mad. I left a long-term relationship partly because they were big on "family", and I hated feeling compelled to spend what always felt like an eternity bored to tears in a house full of people I had nothing in common with at christmas and holidays. Eventually it got to the stage where I just refused to do it, which obviously became a sore point.
I'm perfectly happy doing my own thing on my own, I don't really understand the notion of loneliness because it's not something I've ever experienced, and I think I had to make a choice between spending the rest of my life living with other people or never seeing another human being again, I'd choose the latter. I always find it bizarre how many people, myself included, say things along the lines of you know when you are in a good relationship because you can both be happy ignoring each other for hours on end. Well yes, but there always comes a point where it's impossible to go on ignoring each other, whereas living on your own you can enjoy that peace and quiet indefinitely.
Day out with friends scheduled tomorrow, and then that will probably be the last time I see another human being in the flesh until next weekend because I'm working from home all of next week. Pretty much my ideal.
