In The Common World novel, Mr. Hadley does not write a story in the previous chapter, but he most likely was noticed before the behavior of his son Brinker Hadley. Originally, Brinker's ideas about the war and its place in it are very similar to his father. We see how he reacts to his friend Leper: "This is the place where I participate in a world war," says Brinker, "a school for photographers of beaver dams." It is clear that Brinker's point of view is related to a specific view of what is appropriate for a young man during the war, and it is also clear that the photograph does not correspond to this point of view.
When we finally meet with Mr. Hadley, we clearly see the material from which Brinker made his first views. As Brinker’s contempt for photos and Broadway dams, Mr. Hadley is disgusted when he sees troops in sewing machines included in his equipment. He calls her “girl” and continues: “I can’t imagine that as soon as a person settled on a sewing machine, I can’t imagine it at all. It is clear that Mr. Hadley has a narrow definition of what masculinity can or should be. He scornfully looks at sewing machines, like something under him, and he sees that the people who use them somehow suffer from resentment or humiliation.
Have you ever seen someone who has fundamentally changed his experience? Many films and books about how a traumatic experience can change a person's attitude and character are permanent or bad. Leper is just one example.
