The story doesn't end on the happiest of notes (shocking, we know—it's not like the story as a whole was a laugh-fest to begin with). After the women finish preparing the body, Elizabeth seems to continue to grapple with the fear that washed over her from the moment she learned of Walter's death:
Then, with peace sunk heavy on her heart, she went about making tidy the kitchen. She knew she submitted to life, which was her immediate master. But from death, her ultimate master, she winced with fear and shame. (2.134)
In other words, she seems committed to going about her daily business, but the confrontation with mortality has inspired fear—reasonably enough—and, for some reason, shame.
It's unclear exactly why she would feel shame, but it might have something to do with how topsy turvy her feelings about her relationships have been since she learned of her husband's death. She seems to believe that everyone and everything is more separate than she originally thought, feeling completely alienated from her late husband and even the baby inside of her. Maybe she feels ashamed at buying into this sham of closeness or intimacy, now that it's been revealed as a lie . . . or maybe it something else entirely? Thoughts? Bueller?
