I really don't understand outgoing people very well. In some ways they seem socially insecure in trying too hard to please people. They also seem very pompous, but maybe that's because I am so entirely jealous of them.
You're looking far too much into them. They are just carefree and uninhibited - They do what makes them feel best, what makes them happiest. If everyone stuck by that attitude, we would be happier.
