Two crows challenged each other for a flying competition to see which of them could fly highest, while carrying a sack of even size.
The first crow flew with his sack of cotton and the other was carrying a sack of salt which was much heavier. However, when it began to rain, the salt carried by the second crow began to dissolve, whereas the cotton absorbed the rain water and became so heavy for the first crow. It came fluttering down and accepted defeat.
Moral : Situation changes very fast sometimes.
