[伊索寓言] 幼鹿与妈妈

The Fawn and Her Mother

One day a fawn(幼小的鹿) said to her mother, "You're larger than a dog and swifter.  You also have greater endurance(耐力) and horns(角) to defend yourself...

...But no sooner do I hear a dog bark(狗吠) than I feel faint(眩晕) and take off(逃离，快速离开) as fast as my heels can carry me."

No argument, no matter how convincing(令人信服的), will give courage to a coward.
