In the third section of "A Rose for Emily," what is the main idea and what feeling do you get from it?
Section III of the story details the beginning of Emily's relationship with Homer Barron and, one year later, her mysterious trip to the drugstore for arsenic. The main idea this section conveys is that Miss Emily is still very much an outsider in her town and still very much her own person. She ignores the town gossip about her and Barron, and stares down the druggist until he gives her the arsenic she wants.
This section ends with a feeling of foreboding since we know Miss Emily has purchased a strong poison but do not yet know what she will do with it.
This is the section where Emily becomes involved with Homer Barron a "Yankee" and a foreman "day laborer" and is seen in public with him on Sundays. This is also when Emily buys the rat poison; this purchase gives a feeling of forboding. Emily previously could not accept her father's death and there is foreshadowing that Emily would not accept Homer leaving her; we know that he is not the marrying kind which would be the only option for Emily in this Southern community.
