I really lucked out being born and just not giving a fuck about having friends.
I never cared about it until I met people online and started having fun with them, but even still after all these years, I hardly crave social interaction the same way many people do. People are fun, but it's not like I go stir crazy if I'm alone too long.
Half the time, I talk cuz I'm bored or feel obligated to respond within a certain amount of time. That's something I have to work on, cuz it eats into my time more than I'd like. It's very easy to get sucked in to just reading and replying.
But yeah, I'm very good at keeping myself occupied. I'll watch videos, work on personal projects, play games, fap, nap, whatever. I'll stare at the floor for five minutes, I don't care. Sometimes that's just the mood, you need to stare at something boring for a while, just letting your brain exist.

I know people who are afraid to be alone with their thoughts, cuz it makes them depressed. Fortunately, I can't relate. My mind is a pretty fun place. It's not purely sunshine and rainbows. It can go anywhere from Teletubbies to Terminator. But it's a good playground and I'm not plagued by past regrets.
