In the story, what is the narrator's appearance?
The reader is not given anything concrete in terms of the narrator's appearance. There are intimations given as to how she looks, but overall, there is nothing absolute in terms of appearance description. One articulation about the narrator's appearance is that she is "the tomboy" of the children:
I had always been the tomboy, the live wire, the troublemaker, the one who was going to drive Mami to drink, the one she was going to give away to the Haitians. While the sisters dressed pretty and stayed clean in the playroom, I was out roaming the world looking for trouble.
Such a detail enables the reader to fully grasp why the narrator and Liberty share such a bond. Like Liberty, she enjoys being out in the world and doing what her mother would consider abhorrent. Continuing this description of a tomboy, the narrator details how she takes advantage of her mother's distracted state to not "take a bath" and that she was able to enjoy Coca- Cola instead of her usual boiled milk with beaten egg meal. The narrator is a typical adolescent who enjoys getting into trouble and, like Liberty, instigating the rage within her mother.
