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 pay each other a visit.
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, “ I don’t see any difference.”
