documents: #Person1#: it's a lovely day out today, isn't it?
  #Person2#: it's beautiful. Enjoy it while it lasts. It's supposed to get cold tomorrow.
  #Person1#: what's the weather forecast for tomorrow?
  #Person2#: it's supposed to snow early tomorrow morning and then tomorrow afternoon there's a chance of freezing rain.
  #Person1#: that doesn't sound pretty.
  #Person2#: do you have any plans for tomorrow?
  #Person1#: well, I was going to drive to Birmingham to see some friends.
  #Person2#: you might want to change your plans. With the cold and wet weather that we're supposed to have tomorrow, the roads are going to be rather slippery.
  #Person1#: I suppose I should. I don't like driving in dangerous weather conditions. Do you have any plans for tomorrow?
  #Person2#: I just have to go to class tomorrow afternoon.
  #Person1#: if you're lucky, it'll get canceled and you can have a snow day!
  #Person2#: if that happens, then I'll invite you over and we can drink hot cocoa and watch movies.
  #Person1#: that sounds like fun.
  #Person2#: hey, look outside! It's started to drizzle!
  #Person1#: English weather is even more predictable than I had previously thought.
