No. We all have introverted and extroverted feelings. Even the most outgoing people need alone time.Introverts you mean? I thought that was a introvert thing.
But a true introvert, like myself, would be sick of people time about an hour into socializing. I couldn't do it all day for days on end, and if I did do it I'd be a total rage monster and would probably alienate anyone who tried talking to me.
