answer: Jake needs to buy some clothes for his trip because it snows in the mountains, and #Person1# reminds him to bring a suit.
documents: #Person1#: Hey Jake. Are you ready for your trip?
  #Person2#: Well, not really. I still have to buy some clothes. It's winter there.
  #Person1#: Is it very cold there?
  #Person2#: While the weather doesn't get too cold but it often snows in the mountains. So I'm going to buy a couple of warm sweaters, a jacket and a hat. I don't have room in my suitcase to pack a coat. So I'm going to wait until I get there and buy it when I really need it.
  #Person1#: Do you need any clothing for formal occasions?
  #Person2#: Well, I guess so, you never know when you might need something for a party or a nice date. So I'll probably take a suit.
  #Person1#: Have you forgotten Alice's wedding?
  #Person2#: Oh right, then I'll definitely take a suit.
