It's 5:00 p. m. Mike is driving his new car to his sister's factory. He wants to pick up(接)his sister. But he doesn't know the way. He stops in front of a bank. At this time he sees an old man near his car. Mike comes out of the car and asks the old man, "Excuse me. Where is the factory?" The old man says, "Yes, I know the way to the factory. I can go there with you." The old man is now sitting in Mike's car. Soon they come to a small house and the old man says, "Stop here, please!" Mike stops the car and says, "But this isn't a factory at all." "No," says the old man, "This is my house. I want to get home before dinner. Thank you for taking me home. The factory is behind the bank. So go back to the bank and then turn left. You'll see the factory. You can't miss it." After half an hour, Mike gets to his sister's factory. It's just behind the bank!
