One morning when a vixen was taking her babies out of the lair, she saw a lioness and her cub. "Why do you have only one child, dear dame?" asked the vixen.
"Look at my healthy and numerous children here, and imagine, if you are able, how a proud mother should feel."
The lioness said calmly, "Yes, just look at that beautiful collection. What are they? Foxes! I've only one, but remember that one is a lion."
