I read an interesting little article about each type's "bratty behavior." ESFPs, it said, are entertainers who love the spot light. They can get over eager in their socializing and "are at risk of neglecting their loyal friends" in social situations.

I have an ESFP friend and she has definitely inexplicably ditched me to go be the center of attention amongst some casual acquaintances (they didn't strike me as interesting/unique. But that's just my personal judgement, my opinion isn't objectively true of course).
