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