I think we’ve essentialized the categories of ‘introvert’ and ‘extrovert’ to the point of absurdity. It’s not as if we received an INT v. an EXT stamp at birth. We live in circumstances and and are formed by the pressures of a real, living, and dynamic social situation and our basic coping mechanisms on a daily basis reflect these, as we must fit ourselves to its pressures. Seeing our own basic relating tendencies as intrinsic is kind of a problematic way of looking at human behavior then. http://betweenletters.quora.com/How-to-Live-With-Introverts?ref=fb
