Once to friends were walking through the forest. They knew that anything dangerous can happen to them at any time in the forest. So they promised each other that they would remain united in any case of danger.
Suddenly, they saw a large bear approaching them. One of the friends at once climbed a nearby tree. But the other one did not know how to climb. So being led by by his common sense.
He lay down on the ground breathless, pretending to be a dead man. The bear came near the man lying on the ground. It smelt in his ears, and slowly left the place. Because the bears do not touch the dead creatures.
Now the friend on the tree came down and asked his friend on the ground, "Friend, what did the bear tell you into your ears?" The others friend replied, "The bear advised me not to believe a false friend."
