A example of metaphor and explain the metaphor

Her tears were a river flowing down her cheeks.
As a river is so much larger than a few tears, the metaphor is a creative way of saying that the person is crying a lot. There are so many tears that they remind the writer of a river.

Explanation:

A metaphor is a figure of speech that is used to make a comparison between two things that aren't alike.  They do NOT use the words "like" or "as".

My sister is a devil.
