Which of these quotations from "Miss Brill" represent irony or plot, and why does each one represent irony or plot?Here are the quotations from...

Although it
was so brilliantly fine--the blue sky powdered with gold and great spots of light like
white wine splashed over the Jardins Publiques-- Miss Brill was glad that she had
decided on her
fur.

Irony
is the occurrence of the unexpected in a situation, event, or comment. This first quote
represent irony in "Miss Brill" because, while she loves
her sweet little fox fur necklet, which she calls a "Little rogue," it is the fur that
provokes the ruthless reaction from the "hero and heroine" of the Jardins Publiques, the
reaction that drags Miss Brill from her contented, peaceful dream of a pleasant life of
fresh participation with other like-minded people. Therefore, while the fox is her
happiness and pleasure, it ironically turns out to be her disappointment and
sorrow.

The
day was so charming--didn't he agree? And wouldn't he, perhaps?...But he shook his head,
lighted a cigarette, slowly breathed a great deep puff into her face, and even while she
was still talking and laughing, flicked the match away and walked
on.

This quote also
represents irony because, even while the lady is happily
chatting, the man shows his disdain for her by blowing cigarette smoke in her face and
walking away. This is ironic because, while men smoked in front of women regularly in
the 1920s (the time period of the story), they habitually courteously blew it away from
the woman's face. This irony goes so far as to be the cruel class of irony called
sarcasm.
Sarcasm intends to wound and hurt with ironic words or
behaviors, just as this man intended to hurt--and turn away--this lady.

Both quotes also represent plot because
of how they directly or indirectly reflect on the progress of action and/or
the development of the plot conflict. In the first, the fox is introduced and
it is the fox that creates the conflict when the "hero and heroine" insult it and
undermine Miss Brill's pleasantly settled life of minor happinesses. In the second, the
man's treatment of the lady foreshadows the treatment Miss Brill will encounter in due
time from the ill-bred, heartless, unsympathetic and unfeeling couple: "Why does she
come here at all--who wants her? Why doesn't she keep her silly old mug at
home?"
