In "I've Got Your Number" by Sophie Kinsella, there is a poignant exchange between the characters Sam and Poppy that highlights the theme of self-perception and personal struggle. Poppy believes Sam sees her as a miserable person, but Sam perceives her as someone who is always willing to help others while neglecting her own needs. This conversation reveals Poppy's internal conflict and her tendency to prioritize others over herself, which is a significant issue she must confront.

Sam urges Poppy to recognize that she needs to focus on her own well-being. He emphasizes that nobody should enter a new chapter of life, like marriage, feeling inferior or insecure. The dialogue serves as a reminder that self-care is essential, and individuals should strive to be authentic rather than conforming to the expectations of others. It captures the essence of realizing one's worth and the need for personal growth.
