Why do so many pics of people have to look like they are living it up?

[Bolo]

I been loping across accounts on usual social networking sites and noticed so many girls who are in their early or mid 20's seem to make it a point on their pages of having images of them looking like they are the life and soul of the party and their life is just one long party! with very few images of them just chillin casually and often none! I have a female friend in person who is not one for the party scene and would rather do other things but by looking at her myspace page you would think she was a party animal! she told me the images were years old and were at special occasions. She tells me its because it seems to be a trend these days.

Is she right? I getting a little bored and tired of all these young women (men also) looking drunk and doing silly rapper gang sign gestures with their friends! is there anyone NORMAL out there??? I would expect all this from teens but come on...people in their mid 20's? ffs!!!
