Mr. Brown is 80 years old. Every morning he goes for a walk in the park. And he comes home at twelve thirty for lunch. But today a car stops at his house. Two policemen help him get out. One of them says to Mr. Brown's daughter, "The old man can't find his way in the park. He asks us to take him home by car." The daughter thanks the policemen and leave. Then she asks her father, "Dad, you go to that park every day. But today, you can't find the way. What's wrong with you?" The old man smiles like a child and says, "I can find my way. I don't want to walk home."
