The word “friend” in literature serves as a versatile marker of human connection, embodying everything from sincere warmth and camaraderie to formal, even ironic, boundaries. It can be an intimate term reflecting close bonds and shared confidences, as seen in witty addresses and affectionate banter ([1], [2]), while at other times it carries a weight of duty, respect, or admonition in more serious or classical contexts ([3], [4]). Authors use the term not only to signal genuine affection but also to underline social hierarchies, critique, and the bittersweet nature of relationships, as when a friend’s silence becomes a powerful commentary on guilt or disapproval ([5], [6]). Thus, “friend” emerges not simply as a label for companionship but as a dynamic device that deepens character interactions and highlights the complex fabric of human rapport ([7], [8], [9]).
