The Irony of Millie's job
After a stint in prison, Millie decided to pivot in her career and become a maid for wealthy families across the country. Her first assignment, to the Winchester household, ends in turmoil and misery, forever scarring Millie. Despite this, Millie unexpectedly expresses optimism that she will continue to work as a maid for wealthy families. Typically, people who experienced similar circumstances would not want to continue as a maid and would instead work doing something else. This is likely done to continue the series; however, it also reflects Millie’s commitment to excellence in her craft.
The Irony of Wealth
Despite being incredibly wealthy and very prosperous (materially and emotionally), the wealthy family that Millie works for is anything but that. Where Millie and readers see wealth and prosperity, what lurks beneath is something much more sinister: deceit, violence, and death. This underscores the surprise Millie feels about the family she works for and shows that wealth doesn’t always ensure happiness.
The Irony of Food
Food is typically consumed for two reasons. The first (and primary) reason is nourishment. The secondary reason is enjoyment. Nevertheless, in The Housemaid, food is used for more sinister purposes. Specifically, Millie uses it to control the Winchesters and get a better sense of what is going on in the house.
The Irony of Millie's past
Despite being incarcerated for several years, Millie is hired by the Winchester family to become their maid. Typically, families like the Winchesters are chiefly concerned with appearances and making sure they look as good as possible. Millie's presence in their house goes directly against the expectations of wealthy people like the Winchesters, reflecting their desperation to get help.
