documents: #Person1#: I'm going over to the gym. I want to do some running.
  #Person2#: Why don't you run outside?
  #Person1#: Are you kidding? Do you know how cold it is today?
  #Person2#: Yeah, I suppose. I guess it isn't healthy to run in this weather.
  #Person1#: No, it's not. Not at all. I'd probably freeze my lungs.
  #Person2#: Wait for me a minute. I'll go over to the gym too.
  #Person1#: You?
  #Person2#: Yes, why not? Just let me get my gym clothes together.
  #Person1#: I didn't know you could exercise.
  #Person2#: What do you mean by that? Everyone can exercise!
  #Person1#: Yeah, I know. But you? I always thought you were only good at lifting beer bottles to your mouth.
  #Person2#: No, not at all. I was on the swimming team in high school. And I'd like to do some weight training. They have decent equipment at that gym.
  #Person1#: You're going to lift weights? Hah!
  #Person2#: Are you laughing at me?
  #Person1#: I'm sorry. I just can't imagine you lifting weights.
  #Person2#: Maybe not. But I want to start. I need to get in shape. I feel these past couple months that my energy is low.
  #Person1#: It's true. If a person doesn't exercise, they get sluggish. That's why I keep running. Even in the winter.
  #Person2#: So I need to do something too.
  #Person1#: But lifting weights isn't the best thing. You should do some kind of aerobic exercise.
  #Person2#: I know. But I want to start today with a little weight lifting. Then I'm going to buy a new swimming suit and goggles, and every other day I'm going to go swim laps in the pool. How does that sound?
  #Person1#: It sounds like a good plan to me. I'm still. . . I mean. . .
  #Person2#: What?
  #Person1#: I'm still just surprised you really want to do it. It doesn't seem to go with your character.
