M: May I help you? W: Yes, I want to buy some shoes to replace the ones I am wearing. M: What's wrong with them? W: They are too old and shabby. M: I can see they are simply worn out. Would you like the same color? W: Yes. M: How about this light brown pair? W: Yes, I'll try them on. M: They certainly look charming. W: The trouble is they feel uncomfortable. M: Then try on another pair of the similar style. W: They are much better. Do you have them in red'? M: Yes. Would you like both pairs? W: Yes, if they don't cost too much. M: Oh, no. they don't. The second pair is half price. Shall I put them both in the box for you? W: Just the red and the old ones. I'll wear the new brown pair home.
