In the book Maine by J. Courtney Sullivan, the theme of loyalty is explored deeply. The author suggests that true loyalty is something that is earned through actions and trust, rather than simply inherited through bloodline. This perspective emphasizes the importance of genuine connections and personal effort in forming meaningful relationships.

He also believed that loyalty was earned - sharing a bloodline didn't mean you had to be close. This highlights that familial ties alone do not guarantee loyalty or closeness, and that genuine bonds require more than just shared genetics. Sullivan underscores that authentic loyalty is built through experience, understanding, and mutual respect, rather than mere biological connection.
