Q: Person1: Say , Jim , how about going for a few beers after dinner ?
Person2:You know that is tempting but is really not good for our fitness .
Person1: What do you mean ? It will help us to relax .
Person2:Do you really think so ? I don't . It will just make us fat and act silly . Remember last time ?
Person1: I guess you are right.But what shall we do ? I don't feel like sitting at home .
Person2:I suggest a walk over to the gym where we can play singsong and meet some of our friends .
Person1: That's a good idea . I hear Mary and Sally often go there to play pingpong.Perhaps we can make a foursome with them .
Person2:Sounds great to me ! If they are willing , we could ask them to go dancing with us.That is excellent exercise and fun , too .
