The Bear and the two Travelers

Two men were travelling together, when they met a Bear. One of the Travelers climbed up quickly into a tree and hid himself in the branches. The other fell flat on the ground, and when the Bear came up and felt him with his snout, he held his breath, and lay still as if he were dead.
The Bear thought the Man was dead and soon left him, for bears never touch a dead body.
When the Bear was gone, the other Traveler descended from the tree, and asked his friend what it was the Bear had whispered in his ear.
“He gave me this advice”, his companion replied. “Never travel with a friend who deserts you at the approach of danger”.
Misfortune tests the sincerity of friends.
