Read the following fable by Aesop, titled The Blind Man and the Cub":

There was once a Blind Man who had so fine a sense of touch that, when any animal was put into his hands, he could tell what it was merely by the feel of it. One day the Cub of a Wolf was put into his hands, and he was asked what it was. He felt it for some time, and then said, "Indeed, I am not sure whether it is a Wolf's Cub or a Fox's: but this I know—it would never do to trust it in a sheepfold."

Which is the moral of this fable?

Don't trust a wolf.

Don't trust a sheep.

Evil tendencies are early shown.

Blind men cannot see.
