The Wild Boar And The Fox
Wild Boar was engaged in whetting his tusks upon the trunk of a tree in the forest when a Fox came by.
Seeing what he was at, the Fox said to him, "Why are you doing that, pray? The huntsmen are not out to-day, and there are no other dangers at hand that I can see."
"True, my friend," replied the Boar, "but the instant my life is in danger I shall need to use my tusks. There'll be no time to sharpen them then."
