英语寓言故事 The Ass and the Charger

AN ASS congratulated a Horse on being so ungrudgingly and
carefully provided for, while he himself had scarcely enough to
eat and not even that without hard work.
But when war broke out,
a heavily armed soldier mounted the Horse, and riding him to the
charge, rushed into the very midst of the enemy.
The Horse was
wounded and fell dead on the battlefield.
Then the Ass, seeing
all these things, changed his mind, and commiserated the Horse.
