Pet names serve as a nostalgic reminder of our childhood, providing a sense of innocence and playfulness amidst life's complexities. They allow individuals to connect with a simpler time, emphasizing that life does not always have to take on a serious tone. These names can evoke fond memories and feelings of warmth, highlighting the lighthearted aspects of relationships.

Additionally, pet names emphasize the idea that a person does not have to fulfill every role for everyone in their life. They represent a more personal and intimate side of relationships, allowing for unique connections that are distinct from formal identities. This concept, explored in Jhumpa Lahiri's "The Namesake," illustrates how personal names can shape and reflect one's sense of self within various social contexts.
