documents: #Person1#: Hi, Andy. I am going to Isabel's. Are you coming? 
  #Person2#: No. The things are too expensive there for me. I can't afford it. 
  #Person1#: That is no problem at all. Isabel's is having a clearance sale, and today is the last day. You don't want to miss such a good chance, do you? 
  #Person2#: Really? That's wonderful. Can you wait a second? I need to change. 
  #Person1#: All right, but hurry up. It takes you hours to change. 
  #Person2#: I will. Do you think we can get something really nice and cheap? I mean this is the last day. 
  #Person1#: I think so. They don't sell shoddy cloth for one thing. 
  #Person2#: Should we ask Cindy to come along? She saw the evening gown made of silk last month that she wanted to buy very much. She didn't buy it of course. It would cost her three months' salary. 
  #Person1#: She already bought that evening gown. 
  #Person2#: When? 
  #Person1#: Yesterday. She wore that gown last night, and showed it off to everybody at Mr. Mile's party. 
  #Person2#: Oh? Isn't that like her. 
  #Person1#: Hurry up, will you? We'll have to go to the gas station first. 
  #Person2#: All right, all right. I am ready to go. Let's go!
