Why does Miss Emily refuse for three days to admit that he is dead when her father dies?

Miss Emily refuses to admit her father's death for three days due to her deep emotional attachment and inability to let go of her past. Her father's controlling nature and the isolation he imposed on her left her unprepared for the loss, leading to a denial that reflects her struggle to accept change. This refusal also highlights themes of resistance to change and the impact of grief in Faulkner's "A Rose for Emily."
