Once upon a time in the little pond in a green forest, there lived an ostrich that thought its neck and legs were too long. Ostrich felt silly because it had very long legs and a long neck. It thought that it looked silly. There was also a tricky fox. Fox saw ostrich and wanted to eat it. Fox thought, "Today I need to eat this ostrich." Fox said, "If you do not like your long legs and long neck, I will cut them for you." Ostrich was clever enough to know not to trust fox, and it ran away. So, it was kept alive by its long legs. 
Be glad and satisfied with what we have.
