Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     Hey Claire , you've been really quiet these last few days . Is something wrong ? 
 Person2:  I've been really stressed . It's the end of the year and I've got so much stuff to do ! I feel like I'm drowning in work . 
 Person1:      Well , stress is a real thing . It's not an imaginary condition . 
 Person2:  It's seriously affecting my life ! I can't sleep , I don't have much of an appetite and my husband says I've been kind of short tempered . Other people seem to handle stress okay ... why am I so weak ? 
 Person1:      You're not weak ... you're stressed out ! Stress has been a part of the human condition for millions of years . Back when we still lived in the trees we had to watch out for predators ... and as you might imagine , that was pretty stressful . 
 Person2:  Yeah , but I don't see any tigers or leopards roaming around our office . My stress is just about silly paperwork ! 
 Person1:      But you're actually having the same reaction as our tree-dwelling ancestors ! It's called the flight or fight response . Each time you feel like something's threatening you , your body decides whether to run away or fight ... it causes all sorts of chemical reactions in the body . 
 Person2:  So a deadline will cause that same reaction ? 
 Person1:      It could . Modern humans actually have more flight or fight responses than our ancestors did . They just had a couple of close calls every day , but today , we have dozens or even hundreds ! 
 Person2:  So the life of a cave woman was less stressful than my life ?
