It's pure madness.

I just have to look at my little sister to see how it's spread. She's only 11 and she's already extremely obsessed about her looks - all girls her age seem to be. Her and her friends' perception of beauty is very distorted.. I guess it's becaue they don't know better, but when I and other people (e.g. my parents) try to talk to her about it she naturally won't listen to us because when everybody else her age thinks something is cool or pretty then that's just how it is *sigh*
