It is very easy and good story. once upon a time, in the seasons of summer .One crow was moving here and there in search of water .He was moving hither and thither in search of water .But he did not get water anyway . when he was in search he found one pot with very less water inside it. That crow was very thirsty so, he wanted that water at any cost .But he cant put his beak inside the water and drink it as the water level was too low. He thought what he should do . And finally he got an idea that he should put something inside it so that water level will rise . And his thrust can be removed . He did so, drink water  and flew away
