"Sula" by Tony Morrison is the story of a friendship between Nel Wright and Sula Peace, who are opposites in the way of relating to other people, to the world around them, and to themselves. Nel is rational and balanced; she gets married and gives in to conformity and the town's expectations. Sula is an irrational and transient character. She follows her immediate passions, completely unaware of the feelings other people might have. However, Nel and Sula are able to function well only when they are together because they complete each other as opposites. However, as separate entities, Sula and Nel are vulnerable and isolated from the rest of world; Sula because she is impulsive and disregards the feelings of other people, and Nel because she overlooks her own. .

(44) Sula grows up in the atmosphere of an emotional separation between mothers and daughters in her family. .
The mothers provide only the physical maternal support but lack in the emotional attachment to their children. Sula overhears her mother, Hannah, say, "I love her [Sula]. I just don't like her, that's the thing." (57) Hannah's words act as a determiner of Sula's defiance. Hannah and Eva, her mother, are also alienated. "Under Eva's distant eye, and prey to her idiosyncrasies, her own children grew up steadily." (41) This dissatisfaction causes Hannah to ask Eva, "Did you ever love us?" (67) "I know you fed us and all.
