In "East of Eden," John Steinbeck reflects on the nature of relationships and connections through the lens of a poignant quote. He highlights the melancholy of associations that lack a deeper bond, suggesting that such ties are fragile and insubstantial, merely held together by superficial means. This metaphor emphasizes the importance of meaningful connections in our lives, rather than relationships that are merely convenient or transactional.

Steinbeck's observation urges readers to consider the quality of their connections and the ways in which relationships can be enriched beyond superficial gestures. While postage stamps symbolize distance and formality, they also imply that genuine relationships require more than just surface-level interactions. True bonds are formed through shared experiences, emotional support, and understanding, nurturing a sense of belonging that transcends mere correspondence.
