Why didn't ponyboy care about what randy thought of his house?

Ponyboy didn't care about what Randy thought of his house because he was more focused on the deeper issues at play, such as the struggles between the Greasers and the Socs. He recognized that material possessions and social status didn't define a person's worth. Instead, Ponyboy valued genuine connections and understanding, which transcended the opinions of others, including Randy. Ultimately, he was more concerned with the realities of their lives than with superficial judgments.
