Why does Dee think Mama and Maggie don't understand their heritage?

In "Everyday Use," Dee asks to have two quilts that were made by relatives. However, Mama explains that she plans to give the quilts to Maggie. Dee becomes upset and claims that Maggie will not "appreciate" the quilts and that Maggie will put them to "everyday use" while she plans to display them. Dee places value in the idea of things while Mama places value in the usefulness of things. For example, Dee does not want the quilts that were stitched by a machine, even though Mama says they will probably last longer. Dee has also changed her name from Dee to Wangero because she doesn't want to be named after the people who "oppress" her. Mama feels there is honor in being named after her relatives. Dee feels that Mama and Maggie do not understand their heritage. She makes this claim because Maggie and Mama do not believe as she does. Dee embraces the idea of changing her name and viewing as art those objects that her ancestors made such as the butter dish and the quilts. Mama, however, appreciates those objects because of their usefulness. In Mama's eyes, Maggie will best honor the hand-stitched quilts by using them as they are intended to be used.
