The author thinks there’s a problem with the way society treats boys and girls, like they have to be different in certain ways. For example, we often tell boys to play with trucks and girls to play with dolls. This kind of thinking limits what kids can do and makes them feel like they can’t try things outside of those gender roles. In the story, the author shows what happens when a child, like “X,” grows up without anyone knowing if they are a boy or a girl. This lets the child grow up without being forced into a specific gender role.
