documents: #Person1#: Jack, what's wrong?
  #Person2#: You!
  #Person1#: What are you talking about? What did I do?
  #Person2#: You told Martha that I was on a date? What was that all about?
  #Person1#: No. . . that's not what I meant. I didn't mean that. She asked me where you were and I jokingly said that you were on a date with Sara. I thought Martha knew that you and Sara were just friends.
  #Person2#: She started feeling suspicious after you said that.
  #Person1#: I'm sorry man. I didn't know. I didn't mean to screw anything up.
  #Person2#: Martha gets jealous easily and it took a while to convince her that Sara was just a friend. Now, I have to explain to Sara that I can't hang around her because of you.
  #Person1#: Look. I really didn't mean to, and next time I see Martha, I'll really tell her that you and Sara are really just friends.
  #Person2#: Don't bother.
