Describe Mama's relationship with Dee in "Everyday Use."

Dee can be called the antithesis of Mama: They are opposites in every way. Mama is fat; Dee is thin. Mama is uneducated; Dee has a college degree. Mama loves both of her daughters, but we sense that Mama dislikes Dee; she knows that Dee is embarrassed by her--the way she looks, the way she talks, the way she lives. Dee thinks she is honoring her heritage by assuming an African-sounding name and using old quilts as wall hangings (but don't you think she'll sell them?). She has forgotten that Mama and Maggie are part of her heritage too.
