My wife's birthday is today. I need some flowers.
We have lots of fresh red roses.
How much do the roses cost?
$ 20 a dozen.
That sounds good. Last year I paid $ 30.
Yes, you came here on the right day. They're on sale today.
Give me a dozen.
Very good. Would you like anything else?
No, I'll just give her the roses and a card.
She should be very pleased with these roses.
