a crow was jealous of the raven, because he was considered a bird of good opanion, "let us proceed on our journey, my friend, for it is only the caw of a crow, and her cry, you know, is no omen."

those who assume a character which does not belong to them, only make themselves ridiculous.

乌鸦非常嫉妒渡鸦，因为渡鸦被人们称为灵鸟，能够预言未来吉凶，因此人们总是把关注的目光投向渡鸦。不服气的乌鸦决定也要为自己争取这份荣誉。一天，他看到路上有几个人，就在树上停下，“呱呱”地大声叫起来。过路人听到声音就回头看，正要靠近看时，被他的同伴拦住了。同伴说:“咱们还是赶快离开吧！你没听说过乌鸦啼叫代表将要发生不吉利的事情吗？”

不自量力只能给别人留下笑柄。
