This emotion forces Sylvia to reach down within herself. She wants to go above and beyond her means. She intends to work harder so that she can accomplish her own personal goals. She plans to overcome the injustices of the value-system by working hard and proving to the rich that she is able to do as they do. When people are not given the same opportunities and chances for success and happiness anger is formed within the left-out party.
Anger is an incredibly powerful emotion.
Bambara uses this emotion, not only to interest her audience, but to force them to feel what Sylvia feels. Not always do writers achieve the goal of their work, but Bambara is able to accomplish her goal.
