Me, Myself, and I

For a long time I've noticed that Americans generally talk about themselves all the time. That doesn't mean that Americans are self centered, but it does say something about our culture. We are very self-oriented people that build our lives around what is best for us (and the people we love). In American culture, it is considered the norm to talk about one's self and relate one's personal experiences to other's experiences - this is just the way we interact. Other cultures, however, may hear us and think that we are all self-righteous and conceited because all we do is say me, myself, and I while other cultures speak more of their families, friends, towns, villages, and neighborhoods. Today all I have is a question. What are the pros and cons of talking more about one's life and experiences versus one's friends and families lives and experiences?
