W: I don't know exactly. I think I'm somewhere on New Hampshire Street. I'm calling you from a bookstore. M: A bookstore on New Hampshire Street. It's at a corner, isn't it? W: Yes, it is. And I can see a restaurant at the other corner. M: Now I'm almost sure where you are. You turned at the second corner. You should have turned at the first corner from the railway station. W: Is that so? Then I'll go back to the first corner. M: It'll be better that way. You'll find a one-way traffic sign. That's where you have to turn to the left. Come up the slope to reach a six-storied apartment house. My room is on the third floor. W: I'm sure I won't have any trouble this time. Thanks. M: I'll be waiting for you. Bye.
