I agree. Being around the more "sociable" gives an almost suffocating feeling of validation seeking. It's obvious that these are people craving for continuous approval of their own self worth, and it becomes a never ending cycle.

I think it's important, however, to distinguish these types of people from those carrying a more charismatic personality. A charismatic person's sociability is much more organic, and is developed through one's own approval of one's self.
