what is a good example of sarcasm and a metaphor in the hunger games

Metaphor:

From the first page of the novel we learn about Katniss’s love for her little sister. Rather than tell us explicitly, Katniss relates her feelings by using a metaphor to describe her sister. She compares Primrose to the actual primrose flower and says that her sister is as fresh and lovely as the flower. In this simple yet loving comparison, we get a small sense of the tight bond between Katniss and her sister.
