Stradlater’s composition is supposed to be about a room in a house that can be described. Holden decides to write about his dead brother’s baseball glove because he is deeply depressed about his death and has not come to terms with his grief over the loss of his brother. Allie’s glove, with the green writing on it, is symbolic of isolation.
Allie felt separate from his teammates while playing baseball. Instead of paying attention to the game, he would write poetry on his glove while playing the outfield. The mitt reminds holden of his brother and is the only thing he can be descriptive about so it is what holden writes Stradlater’s report on it. The more Holden focuses on his dead brother, the more alone he feels.
He does not connect with the people around him, but dwells on people who are memories, like Allie and Jane Gallagher. Holden’s deep unresolved sadness over the loss of his brother, a person he tells us was better than him,who should not have died at such as young age, indicates that he feels a sense of guilt over being alive Holden questions why he should still be here, when he brother, who was smarter and kinder than him should be dead.
One of the central questions that Holden asks in the book, and never receives a satisfactory answer to, is how can a young person die and the world, his family, accept it and move on with their lives. Holden is angry at his family for coping with Allie’s death, he is angry at the world for continuing when his little brother died. He is angry at life for being so unfair.
