Once upon a time, two friends were walking through the forest. They knew that any danger 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 huge 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 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 him with his nose, and left the place. It is because, bears do not touch dead creatures. Now, the friend on the tree came down and asked his friend on the ground, “Friend, what did the bear tell you in your ears?” The other friend replied, “The bear advised me not to believe a false friend.”
