Miss Emily met them at the door, dressed as usual and with no trace of grief on her face. She told them that her father was not dead. She did this for three days, with the ministers calling on her, and the doctors, trying to persuade her to let them dispose of the body (529). Emily’s reaction to her father’s death suggests she is not rational.
Another hint that suggests Emily Grierson might be going insane is her social behavior. After her father’s death, she did not associate with anyone in the town except her manservant and, on rare occasions, her distance relatives. Eventually she starts dating a Homer Barron, a “Yankee man” in town on business. Emily and Homer’s relationship came as a shock to the ladies of the town, even a disgrace. After all, Homer did not measure up to the “Grierson” standards. Emily’s relationship with Homer becomes her obsession. After some time, Emily realizes Homer will not marry her. In the end, the thought of her being alone causes her to kill him. Emily kept his body in a bedroom for a long time so she could keep him for herself until her death. It is obvious she had gone mad.
