狐狸和狮子
The Fox and the Lion
狐狸看到一头狮子被困在笼子里，就走到笼子前面，幸灾乐祸地嘲弄他。狮子却对他说：“这不是你在嘲笑我，而是我自己的不幸。”
有时候，机会是有规律的。
A Fox saw a Lion confined in a cage，and standing near him，bitterly reviled him. The Lion said to the Fox，“It is not thou who revilest me；but this mischance which has befallen me.”
Chances sometimes rules.
