The Horse and the Donkey - Aesop's fables

 There was an ass that shares the same stable with a superb horse.

-I do not understand why they give the horse select feed and they put on colorful harnesses;  In the meantime, they put me through hard work, the donkey complained.

And, as if moved by resentment, he added:

-Injustices of life!  It is hateful discrimination, which I will not tolerate.

The next day there were clarified war and the horse was immediately taken out with precipitation.

Suddenly, death laments were heard;  smell of blood and smoke from fires saturate the environment.  Soon the horse entered badly wounded, and the  donkey:

-I'm getting the point.  Now, in my poverty and famine, I continue to live.  Bless my luck!

Fortune is not always one;  move like the moon.
