Aesop's The Bear and the Two Travelers

TWO MEN were hiking in Denali together, when a Bear suddenly appeared on their path.

One of them climbed up quickly into a tree and managed to hide himself in the branches.
The other, not being as quick as his companion, realized that he was going to be attacked by the bear.
He quickly fell flat on the ground.
The Bear came up and felt him with his snout, and smelt him all over.
The man held his breath and remained as still as death.
The Bear soon left him, for it is said he will not touch a dead body.
When the bear was long gone, his friend climbed down from the tree.
Jokingly, he asked his friend what it was the Bear had whispered in his ear.

"He gave me this advice," his friend replied. "Never travel with a friend who deserts you at the approach of danger."

Moral: Misfortune tests the sincerity of friends.
