Child stars like Miley Cyrus are by definition not normal kids, but yet they are supposed to authentically portray normal kids. Basically, they are walking oxymorons.
Even though Miley Cyrus is a 16-year-old, her life is so far removed from the teens and tweens that watch her show and her movies, that she's essentially gazing down at them through thick glasses of fame while standing atop a giant towering pillar made from millions of discarded Mickey Mouse ears. She has no idea what kids today are like. If she did, then she would know that all kids today have ADD (look it up), and there's no way they're going to be able to learn her new ridiculously intricate dance craze "The Hoedown Throwdown" without upping their dosages. Really sensitive, Miley.
