Lily and Ben are twins. They like to play with their toys. They have many cars, big and small, red and blue, fast and slow. They like to race them on the floor.
One day, Mom says, "It is time to go to the park. You can bring one car each. Choose your car and put on your shoes."
Lily and Ben run to their toy box. They look at all the cars. Lily picks a big red car. She likes how it makes noise and has lights. Ben picks a small blue car. He likes how it is smooth and shiny.
They put on their shoes and go to the door. Mom takes their hands and they walk to the car. Lily and Ben put their cars on the seat next to them.
At the park, they see a big hill. They want to race their cars down the hill. They run to the top and get ready.
"Ready, set, go!" Lily says. She pushes her big red car. It goes fast and loud. Ben pushes his small blue car. It goes slow and quiet.
Lily's car reaches the bottom first. She cheers and claps. "I win, I win! My car is the best!"
Ben's car stops halfway. He frowns and sighs. "My car is stupid. It is too slow."
Lily runs to Ben and hugs him. "No, your car is not stupid. It is just different. I like your car. It is smooth and shiny. Do you want to trade?"
Ben smiles and nods. "Yes, I want to trade. Thank you, Lily. You are a good sister."
They trade their cars and race again. This time, Ben's car wins. He cheers and claps. "I win, I win! Your car is the best!"
Lily's car stops halfway. She laughs and shrugs. "My car is not the best. It is just different. I like your car. It makes noise and has lights. Do you want to trade back?"
Ben smiles and nods. "Yes, I want to trade back. Thank you, Lily. You are a good sister."
They trade their cars back and hug. They play with their cars until Mom says, "It is time to go home. You had fun with your cars. You are good twins."
Lily and Ben say, "Yes, we had fun. We are good twins. We love our cars. We love each other." They put their cars in their pockets and hold Mom's hands. They go back to the car and go home.
