No Moral. Suggest us a moral of this fable in comment section.
A Wild Boar stood under a tree and rubbed his tusks against the trunk. A Fox passing by asked him why he thus sharpened his teeth when there was no danger threatening from either huntsman or hound. He replied, “I do it advisedly; for it would never do to have to sharpen my weapons just at the time I ought to be using them.”
