Daniel: Daddy, how are you going to spend your weekends?
Dad: I need to finish my research paper.
Daniel: Could you go with me to climb Xiang Shan?
Dad: Honey, I am sorry I have no time.
Daniel: Oh, Daddy, you should do more exercise. You are getting a little heavy.
Dad: I am afraid you are right. Recently, even going upstairs makes me out of breath.
Daniel: Then go climbing with me, Daddy. Mountain climbing can build your muscles like Popeyes.
Dad: Terrific! It is also a good exercise to keep me fit.
Daniel: I give you my word, you must feel refreshed after mountain climbing.
Dad: OK, I'll go.
Daniel: That's a deal.
Dad: Sure.
