Mike wants to fly like a bird. His father tells him, "You can't fly like a bird because you are too big." "Why can't I? Some birds are big, but they can fly!" The boy doesn't understand. Bill is crippled. He wants to walk and run like other kids. "Why can't I walk or run like other kids?" Bill thinks.
One day, the two boys meet in a park. "Do you want to fly like a bird?" Mike asks Bill. "No," Bill says. "I only want to walk and run like you."
Then Mike walks to Bill's father. He says something to him. "That's OK," says the father. Mike goes to Bill and says, "Get on to my back.Let's run." Then Mike runs with Bill on his back. Bill is very happy and says, "We can fly, Mike! We can fly!"
