documents: #Person1#: What's your favorite sport?
  #Person2#: It's hard to say. Perhaps swimming is my favorite. I like swimming because it helps improve my lung capacity. In the scorching summer days, there's nothing like a cool swim. Currently, I go to the pool twice every week.
  #Person1#: Is the entrance charge expensive?
  #Person2#: Well, it costs an arm and a leg, 30 yuan per person. What a costly sport! That is why I have to refrain from even thinking about it. And I find jogging a very agreeable substitute.
  #Person1#: Haha, jogging? Perhaps it might be a bit too boring?
  #Person2#: You know what? You won't get a rush from it until you fully understand it. It is a simple sport and doesn't require skills of any sort. This leaves room for me to enjoy the beautiful suburban scenery while jogging. Fresh air caresses my face and blows into my chest, which translates into inspirations. Inspirations are really good stuff for a writer like me. Sometimes, I even come up with a verse or two.
  #Person1#: You are really a man who knows how to enjoy being alone.
