Describe symbolism in A Circle in the Fire by Flannery O'Connor

Mrs. Cope's physical attack on the nut grass is not the act of a "worker," as O'Connor points out with the symbol of the sunhats, introduced in the first paragraph of the story: Mrs. Pritchard's is "faded and nut of shape while Mrs. Cope's [is] still stiff and bright and green," indicating that Mrs. Cope is the one who need not wear out her sunhat because she is the one in charge.
