The Crow and the Raven-英文寓言故事

A CROW was jealous of the Raven, because he was considered a bird
of good omen and always attracted the attention of men, who noted
by his flight the good or evil course of future events.
Seeing
some travelers approaching, the Crow flew up into a tree, and
perching herself on one of the branches, cawed as loudly as she
could.
The travelers turned towards the sound and wondered what
it foreboded, when one of them said to his companion, "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.
