answer: #Person1# tells #Person2# the Bill of Exchange can involve different parties and transfer the product automatically. #Person1# tells #Person2# not to worry about it as long as #Person2# has all of the documentation.
documents: #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.
