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:     Hello , is everything alright ? Can I help ? 
 Person2:  I have a Promissory Note , but it's not called that . It's a Bill of Exchange . 
 Person1:      Similar to a Promissory Note , yes . I can deal with that for you right here . The difference between a Promissory Note and a Bill of Exchange is that this product is transferable and can bind one party to pay a third party that was not involved in its creation . 
 Person2:  So , even if someone wasn't directly involved , they can become involved ? Like the bank you cash it in ? 
 Person1:      That's right . We didn't issue it to you , but technically we are buying it from you . So , we become involved . 
 Person2:  I see . Sorry about this , I'm new in this job and I've never even seen one of these before ! My boss just told me to come here and sort it out . 
 Person1:      As long as you have all of the documentation we require you have nothing to worry about .
