Admittedly, it's very self-centered. Like a lot of them try for the big Kardashian show, but even not one example of this kin is actually really exciting.

I don't know if it's just the burden of the age or something else that adds to it - teens like to think they're very individual and no-one else is like them. They do play and they need to play an exceptional role in life.
But in fact they don't - and telling them how much they bore you and how much you say "yeah, heard that a thousand times before", how much you recognize what trends, brands and mass preferences they call "their own ones", it's gonna end you in a spiteful storm. It's like you hit someone with a bat on his head - something completely unthinkable.

These days teens and young adults do a lot of this trending for fame and making it into mass media. Maybe two decades earlier, even adults could still be thrilled and won for this. This has vastly vanished, and those ones which are still there are those which didn't make it earlier or which constantly struggle of remaining being discussed.
