Excuse me. Can you tell me the way to the Public Library?
The Public Library? But there are so many public libraries in London. Which one do you want to go to?
The nearest one.
That's rather far away, too. You'd better take a bus. Take the No. 7 bus to the zoo, then change to the No. 9 bus and get off at the end.
And where's the No. 7 bus-stop, please?
Go straight down the street, and turn left at the traffic lights. Then take the second turning on the right, and you'll find the bus-stop near the corner. You can't miss it.
Thank you very much.
Not at all.
