Earlier quoted context omitted.
>Why do you care? You know, some personality types cannot help but be concerned with how they're perceived by others. They're hardwired that way. It's the classic misunderstanding between extraverts and introverts.
People who don't care about other people's opinions aren't that common and aren't called extroverts. They're generally called sociopaths :-)
Actually the definition of extraversion is deriving gratification from that which is outside the self, so I'd say it's actually introverts who are less likely to care what others think.
