Living through the war, the experiences were just too awful for him. He hated being an adult, he longed for the innocence of childhood. He enjoyed playing and talking to a four-year-old girl, just before his demise. He told her the story of the Bananafish and for their love of bananas, they would inevitably die. There was a delightful dialogue between Seymour and the girl, but not so with the adults that followed. Seymour realized he too could never get his innocence back, so he aimed and fired and that was the end of the Seymour, the adult.
Ginnie Mannox, the main character in Just Before the War with the Eskimos, seemed to be a mature girl. Meeting up with her tennis friend's brother, Franklin, she managed to make conversation. He was much more immature than she, which put them on a level playing field. Though it did seem that the more obnoxious he was the more interested she became in him. Franklin was a crabby type. One could see that he was dissatisfied with his life and was fighting becoming an adult. Although his father wanted him to attend school or work, he did neither. I saw Ginnie feeling that she could help him and nurture him to adulthood. I think this made her feel important. She worked her way into his sister Selena's life to see Franklin again.
