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:     Are you ok ? You seem a bit anxious .  
 Person2:  Yeah , I'm OK , I have been having a lot of mood swings lately . I think it has to do with the pills my doctor prescribed that are causing chaos on my hormones .  
 Person1:      So you mean you feel ecstatic one minute and then blue the next ?  
 Person2:  Yeah , it's weird . For example just this morning I was feeling detached and lonely , even though there was really no reason to feel that way .  
 Person1:      Well , maybe your mood will swing positively and you will feel confident , brave and hopeful !  
 Person2:  I hope you are right .
