What is the author's style in A Christmas Memory by Truman Capote?

The story employs a first-person narrator who is called Buddy, though we are also told that this is not his real name, but a name given to him by his friend. By telling us this, the narrator suggests that the story is not his alone, but also belongs to his friend, the other major character in the story. The advantage of the first-person point of view lies in its allowing us to experience the story as Buddy himself did. The description of Mr. Haha is not an objective view; rather it is the view of a seven-year-old boy: "he is a giant; he does have scars; he doesn't smile."
