There were two trees near a river. A small Sparrow was passing by that way to ask the first three dear trees it is going to rain heavily so can I make nest on your branches for me and my babies. The first three didn't allowed the sparrow and the sparrow flies away. She went to another tree and asked the same question to the tree or so second tree agreed and allowed the sparrow to make nest on its branches. Another day it rained heavily and the first tree broke from its roots and flows down with the rains. When the sparrow saw this, she went and said to the first train you got punished for rejecting me to your rude behaviour. But the tree smiled and replied softly dear, I already knew that my roots were weak and were not able to stand out in such heavy rains. I didn't want to risk you and your young one life. Sorry that I didn't allow you to make nest on my branches saying this the tree flows away. Sparrow felt sorry for that tree and judging it without knowing the truth.
The moral of the story is don't judge a book by its cover.
