I've never read that quote before, but it's cool -- the generational conflict clearly isn't new. I've always been very fond of Frost, too.
Funny thing is, I don't really like my generation. We tend to be disrespectful, entitled, and arrogant. That's part of the reason my best friend is 41. Whenever I hear someone say, "This generation is America's future," I get really nervous. Thankfully, we still have the guidance of your generation, though a lot of them don't like us very much. ;)
