answer: #Person1# and Wendy will go to Isabel's because it's the last day of having a clearance sale. Wendy wants to ask Cindy to come along to buy her favorite dress but #Person1# tells her Cindy has bought it.
documents: #Person1#: Hi Wendy, I'm going to Isabel's. Are you coming?
  #Person2#: No, the things there are too expensive for me. I can't afford them.
  #Person1#: Don't worry. Isabel's is having a clearance sale and today is the last day.
  #Person2#: Really? That's wonderful. Can you wait a second? I need to change.
  #Person1#: Alright, but hurry up.
  #Person2#: Should we ask Cindy to come along? She saw an evening dress made of silk there last month, which she liked very much.
  #Person1#: She is already bought that evening dress.
  #Person2#: When?
  #Person1#: Yesterday. She wore that dress last night and showed off to everybody at Mr. Mile's Party.
  #Person2#: Oh, that isn't like her.
  #Person1#: Hurry up, will you? We'll have to go to a gas station first. We'd better be there before lunch.
  #Person2#: Alright, alright. I'm ready now. Let's go.
