I'm NOT talking the whole... summer camp, learning to dance, "Nobody puts Baby in the corner", etc, although if someone's written THAT, I'd take it :). Sort of coming of age fic, where one partner is older and jaded, and the other kind of grows up.  Prefer Dean/Cas, or Sam/Gabriel, NO Wincest/J2.  AU would probably work the best, but if someone's made it work as hunters, more power to them :D.

TIA!
