The metaphor used to compare her family with a cactus I thought was very powerful use of the literary device. “We were sort of like cactus. We ate irregularly and when we did we gorged ourselves.” I believe this was put into the memoir because it serves as a reminder that cactus are designed to survive on so little and so did Jeannette thought her childhood. It also enforces the idea that they take what they can in order to survive in any means.
