i to am the most out going person i, or the people i know, know. i wouldn't call my self a philosipher, but i hold my own on this site.. right?
i make loud noises in public and have no problem with nudity.
that was a joke.
anyway, i just think that it depends on wether or not they are shy in general. i am most outgoing when my head is cloderd with thoughts. i tend to share them with complete strangers. and i love hitting on atractive women i have never seen before.
