Because:
A: It is the nature of youth to do silly bullshit, because they’re figuring themselves out and being a dick about it ain’t gonna do nobody no good, just leave em’ alone.

B: It’s grownups who’ve got the power and thus it’s their silly bullshit that’s worth getting your undies in a bunch over, because they can actually do some damage.

So you know, kids these days with your penis emoticons or whatever it is now, and your whatever that new popstar who’s name I can’t remember her name is– I just googled the pop charts, it’s Ariana Grande, Ariana Grande is the popstar whose name I can’t remember, and I don’t know whatever trends I as a responsibleadultTM am supposed to object to (is it your pants now?  Am I supposed to object to your style of pants?  Your notions about gender?  Some musical trend I am utterly unaware of?  I HAVE NO IDEA) you go right on doing that, and some stuff, you’re probably right about, because kids are usually right about some stuff because you’re still open to new ideas and cultural change, and that’s awesome, and some stuff you’re probably pretty wrong about because you’re a kid and you’re still figuring shit out, and that’s okay.

Frankly, I gave a whole lot more shits about what teenagers were up to when I was one, and that’s probably how it should be.  Mostly, I think you’re entertaining and kind of adorable.
