Excuse me. Could you give me some directions?
What are you looking for?
A gas station. My car ran out of gas two blocks back.
Walk straight ahead until you come to the second traffic light. Then turn right.
Do you know the name of the street?
I can't remember, but it's the second light.
By the way, do you know the price of the gas now?
I'm afraid I don't. But I do know the price has gone up.
