It's my wife's birthday . I need to buy some flowers for her .   Most women love red roses for their birthday .   How much will the roses be ?   You can get a dozen for only $ 20 .   Now , that's a price that I like .   You're in luck today because the roses are on sale .   Okay , I'll take the roses .   Very good . Perhaps you'd like something else to go with the roses ?   No , the roses are good enough .
