answer: #Person2# tells #Person1# about #Person2#'s experience of working overtime yesterday. #Person1# thinks working overtime is not always pleasant but they have to do it if needed.
documents: #Person1#: You didn't show up in the morning meeting. What's up? 
  #Person2#: Well, I just came in. I worked overtime yesterday. Some statistics and very important documents seemed to be inaccurate. So I stayed to double check them. The boss was aware of my very late work of last night. So before he left office, he told me I could come one hour later this morning. 
  #Person1#: But you still look a little bit tired. What time did you leave? 
  #Person2#: It was around one thirty in the morning. I guess I didn't fall asleep till 3 because those numbers were involving in my mind. I just couldn't stop thinking about them. 
  #Person1#: That's normal after a tense work evening. Working overtime is not always a pleasant experience for me either. Once, I worked overtime everyday for a whole week including the weekend. That really broke my rhythm and I got a little sick later. 
  #Person2#: Working at weekend is something I hate to do most. 
  #Person1#: But if the company asks, what else can we do?
