In the story, Marianne reflects on the nature of work and the exchange of time for money. She replaces a yogurt pot in the freezer and engages Joanna in a conversation about the peculiarity of being compensated for one's labor. This implies a deeper contemplation on how individuals trade their finite existence for the abstract concept of currency, highlighting the often absurd relationship society has with work and money.

This discussion underscores a significant theme in "Normal People," revealing how characters grapple with the meaning of their lives and choices within a system that commodifies their time. Marianne's thoughts prompt readers to consider the value of life contrasted with the pressures of financial survival, inviting a critical examination of how modern society perceives worth and existence.
