Those of us without teenage daughters can fantasize all we like about how cool it will all be when the time comes, including our own remarkable ability to navigate the difficulties described by lesser parents, but all evidence is that there will come a time when K2 realizes that teenagers know everything and oldsters like K1 know nothing. At which point a parent can drive them away or a parent can learn to pick battles. Of course you may be "lucky" enough to have a blamange of a kid who will plod through her teenage years but that seems unlikely- more likely you'll end up with a firebrand who will want everything pierced as a symbol of the tortured world in which she finds herself. ;-)
Sorry, couldn't resist. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
