Dissolve Negativity

Two crows challenged each other to see which of them could fly highest,while carrying a sack of the same size.The first crow filled his back with cotton and laughed at the other crow who had filled his instead with salt which was much heavier.When, however,it began to rain,as the second crow had expected,the salt began to dissolve.The cotton absorbed water and became so heavy that first crow did not even have the strength to fly off the ground and he had admit defeat.
