The correct answer to this open question is the following.
Although the question is incomplete ad dos not refer to any specif story or any kind of context, we can say that it refers to the story "The Man Who Was Almost a Man," written by American author Richard Wright. This story is part of a collection of stories of a book published in 1961 called "Eight Men."
The two themes in the story that interact and build on each other are the theme of desiring to get power to use it and the topic of growing and mature, which is commonly known as coming of age. The story refers to the life of young black men called David, that works in the southern plantations, farming the land. He wanted to have a gun so people could respect him and having the power to use it. When having the weapon, he soon realizes that having a gun does not get him the power and respect he desired.
