Input:  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 ?
