In "A Rose For Emily," what do the appearance of the upstairs room in the Grierson house and the iron-gray hair on the pillow indicate?

Near the
middle of the narrative of "," there is the definition of the sections of the
story:

Thus she passed from generation to
generation--dear, inescapable, impervious, tranquil, and
perverse.

The final section in which the
single grey hair lies on a pillow indicates that all of these qualities ofhave
existed.

• Emily has preserved her lover Homer, a man she has
  cherished and held dear. She has attempted to keep him with her in death as
  she could not in life.
• Miss Emily Grierson has been an
  inescapable part of the community--"a fallen monument." She makes
  sure that Homer, too, cannot escape; she keeps him with her.
• Miss Emily has
  had to be reminded by her kinfolk of her noblesse oblige. But she is
  impervious to this obligation, as she captures Homer. 


• Miss Emily Grierson became tranquil, free from conflict and
  disturbance in the end as she lay with Homer.
• But she has
  been perverse in the way she has keptwith hershe has killed him and kept
  his corpse.

The iron-gray hair upon the pillow next to the
decayed Homer Barron indicates that Emily has slept next to Homer's body. Having been denied so
much in her life, Emily Grierson has grasped what she can from
death.
