Here's why:
* They are ordinary men: They are not extraordinary heroes or villains. They are simple, working-class men who enjoy fishing and spending time together.
* Their motivations are understandable: They are driven by a desire for a day of leisure and escape from the pressures of their daily lives. They also have a sense of camaraderie and a love for nature.
* Their flaws are human: They are not perfect. Morissot is more cautious and conservative, while Sauvage is impulsive and reckless. This creates a dynamic tension between them, making them feel more real.
* Their experiences are relatable: The story deals with themes of friendship, war, and loss. These are universal experiences that resonate with readers.
While the story does have a tragic ending, the characters' humanness and their relatable experiences allow the reader to connect with them on a deeper level.
