Why is Dee angry at the end of the story?

At the end of the story, Dee is angry because she feels that her family does not appreciate their heritage and the significance of the items she desires, such as the quilts. She believes that they should be treated as artifacts of culture rather than everyday household items. Dee's frustration stems from her perception that her family is not embracing their African American identity in the way she deems appropriate, leading to a clash of values and expectations. This anger reflects deeper issues of identity and belonging.
