The Two Friends and the Bear

Two friends, traveling together through a forest and boasting along the way about how they would always stand by each other no matter what danger arose, were suddenly confronted by a large bear stepping onto the path ahead of them. In the instant of shared panic, one friend scrambled up the nearest tree without a word of warning to the other, leaving him alone on the ground.

The second friend, with no time to climb and no weapon to defend himself, remembered hearing that bears sometimes left alone anything that appeared already dead, and dropped flat to the ground, holding his breath and staying perfectly still. The bear approached, sniffed at his motionless body and face for a long, terrifying moment, and eventually lost interest, wandering away back into the trees.

Once the danger had fully passed, the friend in the tree climbed down and asked, half-joking, what the bear had whispered into his ear during those long moments. "He told me one thing," the friend on the ground replied evenly, brushing himself off, "never to travel again with a friend who abandons you the instant real danger appears." The two walked the rest of the way in silence, one of them having learned that promises of loyalty made in comfort mean nothing at all until they're tested by an actual threat — and that the test itself is the only thing that ever reveals which friendships were real.
