the sun and the cave
One day the sun and a cave struck up a conversation. The sun had trouble understanding what "dark" and "dank" meant and the cave didn’t quite get the hang of "light and clear" so they decided to change places. The cave went up to the sun and said, "Ah, I see, this is beyond wonderful. Now come down and see where I have been living." The sun went down to the cave and said, "Gee, I don’t see any difference."
