Here's how it breaks down:
* Max: He gains a sense of self-worth and confidence. Before meeting Kevin, Max felt like an outcast and a burden to his family. But Kevin's acceptance and friendship help him see himself as someone capable of great things.
* Kevin: He gains independence and a sense of belonging. Despite his physical limitations, Kevin yearns for adventure and freedom. Max provides him with both, helping him overcome his fears and limitations.
Together, their "max gain" is the realization that even seemingly ordinary people can achieve extraordinary things when they support and believe in each other. Their friendship empowers them to overcome their individual challenges and reach their full potential.
The term "max gain" isn't explicitly defined in the book, but it's a recurring theme that highlights the transformative power of their relationship.
