Nasha 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. Nasha responded, "I've read about sledding in books, and it sounds horrible. No, thank you." On another day, a different friendly student asked Nasha if he wanted to go out for hotdogs. Nasha responded, "I've read that hotdogs are filled with rat parts and pig bellies. No, thank you." Nobody asked Nasha to hang out again, but he did read about friends in his books.
