By showing people with skewed versions of reality, "A Rose for Emily" asks us to take off our "rose-colored" glasses and look reality in the face. What we confront is the reality of America in the story, and the reality of the main character's complete isolation. Faulkner reveals how difficult it can be to see the past and the present clearly and honestly by depicting memory as flawed and subjective. This "difficulty" is part of why the main characters goes insane, or so it certainly appears. Luckily, there are healthy doses of compassion and forgiveness in the novel. When we start to feel that, we start to see things more clearly.
"A Rose for Emily" shows how the unrealistic expectations placed on southern women in past eras were detrimental.
This story shows how much things have changed since Miss Emily's time, how different our reality is from that of the characters in the story.
