A wild boar was sharpening his tusks on a tree trunk one day. A fox asked him why he did this when there was neither huntsman nor danger threatening him. “I do so for a good reason,” he replied. “For if I am suddenly surprised by danger I wouldn’t have the time to sharpen my tusks. But now I will find them ready to do their duty.”
This fable shows that it is no good waiting until a danger comes to be ready.
