I've always been an introvert. I'm very content being on my own, though I do also like a certain amount of social contact (just a bit), to prevent too much self-absorption and to be inspired by other people's ideas and attitudes.
I'm also a gregarious person, meaning I enjoy mingling with crowds of people because it feels safe and cosy. I like watching and listening to them. But I don't want to talk to all these people (how on earth could I?), I just like them being around.
Because I like my own company, I'm not good at making friends. The need isn't urgent enough to trigger the necessary socialising and making connections. So I have loads of online and offline acquaintances but no close friends apart from Jenny.
I'm not a misanthrope. I don't detest other people. I don't prefer animals to humans (yet). I don't have some sort of perpetual grudge against humankind. I'm interested in other people and their foibles and hang-ups and idiosyncracies. I'm just not curious enough (nosy enough?) to actively befriend them.
So am I a healthy or unhealthy introvert? Do I spend too much time on my own? Am I too self-absorbed? Am I too detached from other people? Do I have reclusive tendencies? What's the yardstick exactly?
I would define an unhealthy introvert as someone who hardly ever leaves the house, who basically dislikes other people, who maybe is afraid of them and thinks they're up to no good, who shuns their friendly or solicitous gestures.
Hopefully I'm a long way from such a desperate lifestyle.
