The author Roald Dahl used hyperbole to make the meaning of the sentences stronger. The author used hyperbole in the second page to tells the readers about how crazy the woman is.For example: "And once she chewed her boy friend's nose." (Dahl, line 7)The author used hyperbole here because the author wants to tell the reader how crazy is the woman. Also, the author used it here because the author might want the readers to know about the real issues i this poem and also make the important part stands out in this poem. The author used this poetic device well by making the important part of the poem be more obvious.
