Excuse me. Could you tell me how to get to the library?
Of course. It's on Memorial Avenue.
On Memorial Avenue?
Right. You know where that is?
I'm afraid I don't. I'm quite new in town.
Well, do you know where the post office is?
No, I don't. But I do know where the shopping mall is.
That won't help us. Let me see now. . . Why don't you follow this street, Elm, until, you get to the second stoplight.
