Very much introvert, but am a great socializer when in the mood. I keep all important things inside and let others think they know me by the outgoing persona I have developed while working with the public. A bit screwed up but a necessary protection device I set up to reduce the amount of being hurt by other people.
Introverted. I have to be very comfortable to be sociable with people. Also, if I'm in an area where I -don't- know many people, I have a tendency to not approach anyone. I wait for others to approach me. I just am not comfortable with approaching.
