Ben and Lily are young. They like to play outside. They get exercise when they run, jump, and kick a ball. They have fun with their friends.
One day, Ben and Lily see a big dog. The dog is brown and furry. It has a long tail and a collar. The dog is friendly. It wags its tail and licks their faces.
"Hello, dog!" Ben says. "What is your name?"
The dog barks. It sounds like "Rufus".
"Rufus, do you want to play with us?" Lily asks.
The dog nods. It runs after the ball. Ben and Lily run after the dog. They get more exercise. They laugh and shout.
"Rufus, you are a good dog!" Ben says.
"Rufus, you are a fast dog!" Lily says.
The dog barks. It sounds like "Thank you".
Ben and Lily hug the dog. They are happy. They have a new friend.
