What details of the story are especially significant?Kate Chopin's "The Story of an Hour"

In this compact narrative, Kate Chopin skillfully and
meaningfully makes use of many pregnant details. For instance, it is interesting how the
initial reference to Mrs. Mallard changes to "she" after the woman is informed of the
death of Mr. Bentley Mallard.  Thus, the focus of characterization switches to the
feminine aspect in contrast to the Victorian setting of femme covert
in which a woman/wife called "Mrs. Mallard" is subservient to her husband. 
And, as "she" looks out her window, realizing that Spring approaches, a season that
parallels her own burgeoning feelings of independence, the emergence of "Louise," the
individual occurs in contrast to the former "Mrs. Mallard" as her sister Josephine calls
to her outside the bedroom door.

Also, while "she" is in
the bedroom emerging as an independent individual, there are such adjectives used as
"acquiver," "delicious" "twittering," "approaching"; these details suggest the spiritual
awakening, the "monstrous joy," of the main character as she realizes her new-found
freedom.   However, as the detail of "monstrous" suggests, the dream of freedom is
short-lived for Louise as her "feverish triumph" turns to a fatal defeat with the return
of Brentley Drummle and "she" changes to "his wife" in the third-to-the-last line.
Certainly, Kate Chopin's "A Story of an Hour" utilizes details most
significantly.
