There once was a young man who traveled off to far and distant lands, expanding his horizons, learning new things, meeting fascinating people, and acquainting himself with the ways of the world.
Then, in accordance with custom, that certain young man returned to his home, his family, to bring tidings of the wider world. "Hark!" the young man proclaimed, "There is more to this world than I was ever taught. Some things that I once thought were right I now see as I wrong. I have learned that love is stronger than hate, cooperation more vital than competition."
But that young man's words fell on deaf ears in his homeland. That young man's family turned their heads at his education and experience. The young man had re-entered that world from which he came, and found that he didn't recognize it anymore. And that young man wept bitterly and departed his ancestral home as a very old man.
