Miss Emily's father was a protective "gentleman", effectively enforcing a policy of exclusion around his daughter. While alive he believes that no one in Jefferson is good enough for Emily and she must be protected from shame, dishonor and from those who are beneath her station.
The result of this protective policy is a cloistering. Emily is isolated from the community, growing reclusive. Emily's father keeps her from achieving a normal life and kept from finding a husband.
It is his influence that deprives her of a husband when she is young...
When he dies, Emily "clings to that which robbed her", continuing her reclusive isolation and living a cloistered life.
...after his death, Emily continues to isolate herself from the rest of the community for the better part of her life.
As it was Emily's father that taught her to be alone, enforcing this state as well, he is responsible for what becomes Emily's permanent habit of solitude.
As was mentioned in the previous post, Emily's father was extremely protective of his daughter and did not think that any citizens of Jefferson were good enough to court her. Mr. Grierson was controlling, and Emily lived in his shadow her entire life. When Emily's father died, she refused to accept the fact that he was dead for three days. After he died, Emily rarely left her home. Her father also had an extremely negative impact on Emily's mental state. She feared leaving the comforts of her home and was isolated because she did not have a relationship with any man. The portrait of her father clutching a horsewhip in the foreground while Emily stands in the background represents their relationship. He was an oppressive figure who left an indelible impression on his daughter. Emily was never able to have a loving husband because of the way her father prevented her from having a relationship with anyone. She also remains isolated after her father's death and is prevented from living a fulfilling life.
Well, here's my idea: Emily's father must be a perfectionist. You can see that in how he drove away all the young men that came for Emily. He must also be a strict person, rule-abiding, and you can see that in how Emily never dared to resist his words.
I'm sorry I can't do much for you, and if I made up some words. I wish you good luck on your essay though, and those are what I can think of.
