A Real Life Fairytale

I'm not sure when or if we are supposed to post our stories, but here is mine.

I knew this girl whose best friend goes to college somewhere in southern California. She has a roommate who happened to be the daughter of some wealthy, big shot, Hollywood manager guy. Consequentially, she got invites to all of these big time parties and the two of them would go on occasion. One night, they were having a grand 'ole time partying among the celebraties when they came accross a famous muscian (I forgot who it was exactly, let's call her Helga). Unaware that the two girls were mere college kids, the three of them quickly became good friends. After that night, they exchanged phone numbers, and the following weekend were invited by their muscian friend to countless other "A" list parties. A month or so went by and the ladies had partied with pretty much all of Hollywood. One night, after far too many margaritas, the girls spilled the truth about their identies. To their superise, their famous friend was almost relieved. In fact, she opted that one of them  switch places with her for a day. The girl whose dad was wealthy happened to look strikingly similar to Helga, so they decided to switch the following weekend. The weekend came, and the girls went on their ways being eachother. At first, the girls had a blast meddling in the life of the other, but when the day came to an end, they both discovered how lucky they really were to have the lives that they both had. Being in the shoes of the other opened both of their eyes into seeing that they need not take advantage of what they have. After that, the girls kept in touch and hung out every once in a while. But after the switcharoo, my friend's best friend said that she noticed a change in both the girls: they were more grateful, gracious and kind.
