answer: Susan finds Peter hasn't driven for a long time. Peter says he rides to work now because he feels revived when riding to work with fresh air and he will continue riding.
documents: #Person1#: Peter, where is the ear? I haven't seen you drive to work for a long time! Is it broken or stolen?
  #Person2#: Hi, Susan] Oh, no! Of course not! I give up driving to work. Instead, I ride to my working place.
  #Person1#: Why is that?
  #Person2#: You see. There is only a stone's throw from my home to my working place. I think riding a bike to work is more convenient.
  #Person1#: I don't think so. It will take you at least 25 minutes to get to our company from here.
  #Person2#: Yes, sometimes, 30 minutes. But I love riding to work now. It is a totally different picture on my way to work.
  #Person1#: Why do you think so?
  #Person2#: You see, every morning, after I set off for work, I can breathe the new fresh air along the way. By the time I reach my office, I feel rather revived. I even don't rely on coffee to spend my morning hours.
  #Person1#: Is it so magical?
  #Person2#: At least, that's how I feel about riding to work. I can't believe I have wasted so much fresh morning air in the past 3 years!
  #Person1#: Will you continue riding to work in the future?
  #Person2#: I think so.
