"Is there something I can do for you?"
You seem upset.
"You're right. And I don't see how you talkiing to you is going to help."
"Sorry, I'm having a terrible day. My partner and I were getting ready to close a very profitable trade deal when all my papers were stolen! I think I was pickpocketed."
Can I help?
"I suppose you could kill me. Yes, one swift swing of your weapon and then I won't have to worry about this anymore."
"No, no. I'm just kidding. Mostly"
Where did you see your papers last?
"In my pocket, of course! That's why I think I was pickpocketed!"
"Look, I understand you're trying to help, but there's nothing you can do. Just leave me alone! I'm just ... I just have to think."
