The audience can understand that boys were taught to have a dominant, masculine energy at such a young age. If the audience thinks about Holden and his characterization throughout the whole novel, they will clearly realise that the main character, who is a boy, wasn’t described as much as a manly figure. Also, this indicates one of the topics that Holden is different among his peers and creates the question “whether he will be accepted, or not?” which is about the theme of isolation.
