Can you tell me where the book A dream of red mansion is?
I'm sorry it's been lent out. What about this one? It's a newly published novel written by a young writer. It has a fast paced plot and the language is easy to read.
OK. I'll take it. By the way, how long can I keep it?
3 weeks. You can come back and borrow it for longer if you can't finish it in time.
How long can I keep the novel the second time?
The same. 3 weeks. But you can only borrow it twice within a year.
