I fear, though, that your piece ignores the decent possibility that this question is being asked simply to see how it will be answered. The question would, in the best case, elicit attitudes toward storytelling and, yes, a sense of storytelling fluency even if the question itself is unanswerable. I suspect those with a strong sense of storytelling (who are not trying to prove a point) would come forth with some very interesting premises in their attempts to answer a question that, I agree, is in the end unanswerable. The Sphinx’s question had a specific answer — a destination, if you will. For this question, it’s the journey that reveals the traveler’s heart, and that to me is what makes it a worthwhile thing to ask.
