Reread the following passage from The Outsiders. In this excerpt, Ponyboy has been fighting with his brother, Darry, which upsets his other brother, Soda. He gave us a pleading look. "Golly, you two, it's bad enough having to listen to it, but when you start trying to get me to take sides . . ." Tears welled up in his eyes. "We're all we've got left. We ought to be able to stick together against everything. If we don't have each other, we don't have anything. [ . . . ] And that's worse than dead. Please"—he wiped his eyes on his arm—"don't fight anymore." Darry looked real worried. I suddenly realized that Darry was only twenty, that he wasn't so much older that he couldn't feel scared or hurt and as lost as the rest of us. I saw that I had expected Darry to do all the understanding without even trying to understand him. And he had given up a lot for Soda and me. "Sure, little buddy," Darry said softly. "We're not going to fight anymore." "Hey, Ponyboy"—Soda gave me a tearful grin—"don't you start crying, too. One bawl-baby in the family's enough." "I'm not crying," I said. Maybe I was. I don't remember. Soda gave me a playful punch on the shoulder. "No more fights. Okay, Ponyboy?" Darry said. "Okay," I said. And I meant it. Darry and I would probably still have misunderstandings—we were too different not to—but no more fights. We couldn't do anything to hurt Soda. Sodapop would always be the middleman, but that didn't mean he had to keep getting pulled apart. Instead of Darry and me pulling him apart, he'd be pulling us together. "Well," Soda said, "I'm cold. How about going home?" "Race you," I challenged, leaping up. It was a real nice night for a race. The air was clear and cold and so clean it almost sparkled. The moon wasn't out but the stars lit up everything. It was quiet except for the sound of our feet on the cement and the dry, scraping sound of leaves blowing across the street. It was a real nice night. I guess I was still out of shape, because we all three tied. No. I guess we all just wanted to stay together. From S. E. Hinton, The Outsiders. Copyright 1967 by S. E.
