A: Excuse me, Do you carry books on Chopin?

B: I think we do. Just a moment. How about this one?

A: Umm.... I've already read it.

B: Then I recommend a magazine which has Chopin as its cover story this month. It'll be issued the day after tomorrow.

A: I'm afraid I don't have time to be here on that day.

B: Oh, then, (                         )

A: I was thinking about doing that. OK. I will.
