> Some people actually willingly go down into a crowded basement club with loud music and not just as some kind of tough challenge to survive and shape your character to have tbuilt tolerance for that harsh environment,but they find it enjoyable, no matter how baffling it seems to the rest of us.

The funny thing is that I used to go clubbing regularly because to me that was not about socialising per se. I'd be happy to go alone into an anonymous mass of people and just dance and switch off. I'd still need time to recover, but not nearly as much as with a group of people I'm expected to talk to.

That's universally held for me in other contexts as well. E.g. I can speak in front of thousands - and have - and not stress out at all. They're a non-descript mass at that point. I'm just talking, not conversing. But if any of them try to corner me to talk to me afterward? That is exhausting.
