It was beginning to get dark. We were still not home yet. I bet Dad is going to be mad at us, I thought. I yelled at my brother to ride his bike faster, but it was difficult to ride bikes uphill. I was so tired that every muscle in my legs were burning. My brother finally got off his bike and sat down. I stopped and went back to help him. Suddenly, there was a car coming toward us. I could see headlights. It was Dad. He had come to look for us, since we were so late getting home. I knew I was going to get into trouble, but at least we were safe. Dad picked us up and took us home.
