y free-spirit chicks with their happy hours and girly myspace pages......?

Why do some girls feel like they have to project this image (some are fake) like they are it????? They go to Friday happy hours (only with the best looking girly friends), road trips to Cabo and Cancun, scuba diving, jogging 10K's, and myspace and Facebook pages that exaggerates their career/jobs (some claim they make over $100,000/year) and fake friends, yet if you were to meet any of these girls, you would probably find them to be quite shallow in intellect and social ability. In fact, yesterday I saw this one girl's myspace page with all these cute girly pics on her "friends" section.
