answer: Mike was busy recently but he's finished all the work. Mike and his wife will go to his in-laws' to celebrate Mike's birthday, while #Person1#'s in-laws will come to #Person1#'s house to celebrate Christmas.
documents: #Person1#: Hey, Mike. Where have you been? I didn't see you around these days?
  #Person2#: I was hiding in my office. My boss gave me loads of work to do, and I tried to finish it before my birthday. Anyway, I am done now. Thank goodness! How is everything going with you?
  #Person1#: I'm quite well. You know, tomorrow is Christmas Day. Do you have any plans?
  #Person2#: Well, to tell you the truth, I am more than excited about my birthday, which will come in two days. I am going to visit my parents-in-law with my wife.
  #Person1#: Wow, sounds great.
  #Person2#: Definitely! This is my first time to spend my birthday with them.
  #Person1#: Do they live far away from here?
  #Person2#: A little bit. We planned to take the train, but considering the travel peak, my wife strongly suggested that we go to the airport right after we finish our work this afternoon. How about you? What's your holiday plan?
  #Person1#: Well, our situations are just the opposite. My parents-in-law will come to my house, and they wish to stay at home and have a quiet Christmas Day. So I have to call my friends to cancel our party that will be held in my house.
  #Person2#: You'll experience a quite different and lovely holiday. Enjoy your Christmas!
  #Person1#: Thanks, the same to you!
