answer: #Person1# and #Person2# are blaming each other for the car accident.
documents: #Person1#: Watch out! You'll hit that car if you're not careful.
  #Person2#: Oh no, I won't. But we will have an accident if you don't stop shouting.
  #Person1#: You see. I told you you'd hit him if you weren't careful.
  #Person2#: Oh, shut up, will you? It was all your fault. If you'd kept quite this would never have happened.
  #Person1#: Oh, so it was my fault, was it? If I hadn't warned you in time it would have been much worse.
