What is an example of a metaphor from The Pigman?

One striking metaphor in The Pigman is in the following passage:

"And when I came up to the cage to see these ugly blood-sucking creatures, I had to look right into this little kid’s face that had a smirk on it. He made me feel as though I was a bat in a cage and he was on the outside looking in at me. It all made me very nervous" (page 62).

In this passage, in which Lorraine is looking at caged bats in the zoo, she uses a simile (a comparison that uses "like" or "as") to compare herself to a caged bat, but the comparison of herself to a caged animal runs through this passage and is a metaphor. She is like a caged animal because she lives with her mother in a very unloving and restricted environment in which her mother monitors nearly her every movement. 

Another metaphor is "The Pigman, John, and me--three little monkeys" (page 101). Lorraine compares John, the Pigman, and herself to three little monkeys while they are roller skating. They are similar to the three little monkeys that they see in Beekman's pet store hugging each other in desperation. The monkeys cling to each other for support, just as John, the Pigman, and Lorraine cling to each other because they don't receive much love from anyone else.
