Whats the theme of this short story: Ulysses spent all his free time reading books and felt that he was very intelligent. One day a nice student from his class asked him if he wanted to go sledding. Ulysses responded, "I've read about sledding in books, and it sounds miserable. No, thank you." On another day, a different friendly student asked Ulysses if he wanted to go out for hotdogs. Ulysses responded, "I've read that hotdogs are filled with rat parts and pig bellies. No, thank you." Nobody asked Ulysses to hang out again, but he did read about friends in his books.
