my mom is chinese. And my dad is chinese. I guess that would make me... chinese.

I've discussed with my sister about social anxiety - she has it as well, and we both think there are cultural factors involved. Things like how in the culture, it is polite to say the elder's name really loud... And the louder you say it, the more polite you're being... We think things like this contribute to fear of authority. Cuz if you were to not say it, then my mom would give us looks like we were bad kids. But when you're a kid, you're naturally shy and scared of adults and authority.
I'm sure i'ts not the only thing, but i'm sure culture has something to do with it.
