Lily and Sam are friends. They like to play with their bicycles. They have a race on the street. Lily is fast, but Sam is faster. He wins the race. "Yay, I win!" Sam says. He is happy. Lily is sad. She wanted to win. She cries. "Hey, don't cry," Sam says. He is nice. "You are good too. Do you want to play again?" Lily nods. She wipes her tears. She smiles. They play again. They have fun. They are careful. They don't want to get hurt. But then, a big dog runs out of a house. It barks. It chases them. Lily and Sam are scared. They pedal faster. They try to get away. But the dog is faster. It catches up with Lily. It bites her bicycle. It makes a hole. Lily screams. She falls off her bicycle. She hurts her knee. It bleeds. Sam stops. He turns around. He sees Lily. He is worried. "Lily, are you okay?" he asks. He runs to her. He helps her up. Lily is not okay. She is hurt. She cries. The dog runs away. It is afraid. Sam hugs Lily. He is sorry. "I'm sorry, Lily. It's not your fault. The dog is bad. You are brave." He gives her his bicycle. He says, "Here, you can have my bicycle. You can win the race. I don't need it." Lily is surprised. She is grateful. "Thank you, Sam. You are kind. You are a good friend." She takes his bicycle. She says, "You are a good friend too. You can share my bicycle. We can both win." They hug. They smile. They ride together. They are happy.
