It is easy to be brave from a safe distance.明知无危险,偏要逞勇敢.
是伊索寓言名言警句：
The Wolf and the Kid
A Kid was perched up on the top of a house,and looking down saw a
Wolf passing under him.Immediately he began to revile and attack his
enemy."Murderer and thief," he cried,"what do you here near honest
folks' houses?How dare you make an appearance where your vile deeds
are known?"
"Curse away,my young friend," said the Wolf.
"It is easy to be brave from a safe distance."
