They're walking train wrecks. The are the constant butt of jokes, the people who can never get anything right. Since they are all in the pop-culture spotlight, we know about their mistakes. Every day people may bite the ears off of other people, but nobody else ever knows about it because they're not famous. So as I gaze at life strictly as an observer, I notice something.
Ordinary people can screw up.
There are consequences for really wrong things, sure. Adults are trusted with much more responsibility than young people. Nope, just that they're older. It would then make sense to say that being a non-famous teenager puts kids in a nice position should they screw up. And that is the best thing about being a teenager.
