Amych, on introversion:
It's like your shields in a video game -- you have a certain number of hit points you can take (or other humans or units of interaction or stresses or embarrassments or whatever) before your defense goes critical and you have to withdraw to repair/recharge/whatev. And the thing is, some people can have pretty badass shields and go in swinging and not really care, and even really truly *like* the interaction, but when they reach that point, gotta make repairs. And some people don't have a lot of defense at all, but they're good at picking their tactics and engagements and make it through. And... okay, I'm a big dork, am'n't I?
