A traveller made a long, arduous journey to find a hermit who was reputed to be extremely wise.
After searching the wilderness for many weeks, he finally found the old man in his hideaway.
"Tell me about life," said the traveller.
"Well," said the hermit, "Life is like a fish."
The traveller thought on this for a while, then said to the hermit, "How is life like a fish?"
The hermit sat silently, pondering the question.
Minutes turned to hours, as the sun moved across the sky and sank towards the horizon.
Finally, the hermit said, "Okay, maybe life isn't like a fish?"
