In the book "The Hunchback of Notre-Dame" by Victor Hugo, a conversation takes place where one character asks another if they understand what friendship truly means. This moment illustrates the deep significance of companionship and the unique bond that can exist between people. The Roma character shares a meaningful perspective on friendship, comparing it to the relationship of siblings. He expresses that true friendship involves two individuals who are close and supportive, akin to fingers on the same hand, yet maintain their individuality and autonomy. This metaphor emphasizes the importance of both connection and personal space in a genuine friendship.
