Dad , where is the Book Building ?   I'm looking . Can you still remember what the conductor said ?   She said that when we get off the bus , the Book Building is right by the bus stop .   But I don't see it .   Oh , Dad , look at the sign , please !   Oh , my god ! We get off at the wrong stop . I'm so sorry , honey .   OK , Dad , it happens .   It's my fault . So what can we do now ? Walk ?   Come on , I'm too tired !   OK , you promise don't tell your mother about it , we'll take a taxi .
