Model: A: Excuse me. Do you know where I can mail a letter?
B: Sure. There's a post office on River Road.
B: Of course. Go to the 5th floor. There is a toy shop.
B: Restroom? Oh, it's on the other side of the road.
B: Yes. Go past the hotel. You'll see an underground parking lot.
B: Oh. The nearby cinema is 2 kilometers away. You'd better take a bus there.
B: Look, beside the children's clothes store is a flower shop.
