Final answer:
The student seems to be confused between 'A Good Man is Hard to Find' and 'A Rose for Emily.' In the latter, Homer's body is found in a locked room on a bed with a single grey hair on the pillow, revealing the protagonist's morbid attempt to keep her loved one by her side.
Step-by-step explanation:
In 'A Good Man is Hard to Find' by Flannery O'Connor, there is no character named Homer; it appears there might be some confusion with another Southern Gothic story, 'A Rose for Emily' by William Faulkner. In Faulkner's narrative, Homer Barron is the suitor to the protagonist, Emily Grierson, and at the end of the story, it is discovered that Emily poisoned Homer and kept his body in an upstairs room of her house.
His body is found in a bed in a locked room, which had presumably been untouched for decades, indicated by the single grey hair found on a pillow next to the corpse. This discovery is a significant twist that illuminates Emily's extreme psychological response to abandonment and her inability to let go of a loved one, reflecting themes of decay and obsession.
