　　The weather was fine last night. My friend named Steve and I decided to sleep in the open air. I found the sleeping bags under the bed in my room. I also packed some snacks(零食). We could hardly wait for it to get dark. We opened our sleeping bags and put them on the grass in front of my house. Steve and I played some games, talked about something interesting and had a snack. In the end it got dark. We were just falling asleep when we heard something unusual.

　　“Maybe it is just a small animal,” I said. Steve said nothing, but I could feel he was frightened. After I looked around, I was sure it wasn't an animal. It was my little brother, Tommy.

　　“What are you doing here?” I asked. “You know, Tommy, you frightened us.”

　　“Sorry, Bill,” he said. “It's hot in the room. I want to sleep outside with you.”

　　“Well, OK,” I said. “Just come and lie down next to us.”

　　“Good night, Bill and Steve,” said Tommy. “And thanks.”
