The House on Mango Street is a novel narrated by Esperanza who, along with five members of her family, move into a barrio and must live in a red house that does not even have running water. She is so disgruntled with this house that she wants to go somewhere else. She narrates,
Someday I will have a best friend all my own. One I can tell my secrets to. One who will understand my jokes without my having to explain them. Until then I am a red balloon, a balloon tied to an anchor.
In this metaphor Esperanza compares herself to a red balloon because her house in painted with red paint and it resembles a balloon that is tied down because she is trapped in that barrio with no hope for her future.
Then, Esperanza remarks that she and her sister are alike in several ways, one of which is their laughter, which is
Not the shy ice cream bells' giggle of Rachel and Lucy's family, but all of a sudden and surprised like a pile of dishes breaking.
In other words, her sister's and her laughter are not light and giggly, but sudden and crashing, like dishes breaking'
Another example of metaphor comes when Esperanza goes to "Elenita, witch woman..." who reads the tarot cards. After she deals some out, she says,
Here a pillar of bees and this a mattress of luxury
These are metaphor for hardships and times of comfort.
