Bookseller: We have hundreds of books about birds. What kind of birds were you thinking of?
Customer: Birds that don't fly.
Bookseller: Ah. Over there on the shelf you'll find books about penguins, emus and ostriches.
Customer: Thanks so much.
(The customer starts looking at the books)
Bookseller: Do you like those books?
Customer: They're wonderful. It's hard to choose. This one is really interesting. This one has beautiful pictures. That one is fantastic but it is too expensive.
Bookseller: Oh, but that one is on sale. Half price today!
Customer: Really?
Bookseller: Yes. And the one with the pictures is on special offer; if you buy one you can get one free. And the penguin book is not expensive at all.
Customer: Then I think I will be able to buy all three. Wow!
Bookseller: And you will know a lot about birds if you read them all!
Customer: Thanks for helping me.
Bookseller: Thank you. Remember, in July we will have a really special sale on all our books. Come back and visit the store again!
