How does the writer presents the relationship between brother and doodle in 'The Scarlet Ibis'?

Doodle is different from everyone else right from the start of the story, and the narrator has trouble accepting that. He cannot cope with the fact that Doodle does not fit with his image of a perfect younger sibling. When he pushes Doodle into learning physical skills, he threatens him with the thought of being different from everyone else when he starts school. But "different" does not necessarily have to be bad; Aunt Nicey is the one person who consistently claims that Doodle's differences make him special, not a pariah.
