Life lessons are everywhere, if you look for them. An observant and intelligent young man or woman will learn from not just those around them, but from the highbrow literature and media that they consume.
But this is 2015, dammit! Kids don't take their best girl to the malt shoppe and then try and sneak a grope at Makeout Point, they just use Tinder and say the hell with it. And while we'd rather #teens consume Madame Bovary instead of PewDiePie, we can't sweat it. What kids like are going to be what adults like for the next twenty years or so, until what they like is supplanted by some weird cyborg-AI that directly implants messages into your brain about which boxed ravioli to buy.
