There is a word I hear thrown around frequently called the ambivert. These people are a combination of both #introvert and #extrovert. To be honest I think people are a combination of both. I have a socialization tank that diminishes as an evening of social buzz ensues. Perhaps there needs to be a social hub or social boxing ring in the center of the room and once you have exhausted your resources, everyone should have a pair of shades and a set of Beyerdynamic headphones they can pop on as a universal sign that they are tapping out. Usually if I can have moments of reprieve I can bounce back and enjoy the scene.
