Task: Dialogue State Tracking
Input (English): Buyer: Hi great bike, I am looking for one like this for my son. Has it ever been used?
Seller: Nope, brand new. I even assembled it
Buyer: Why are you getting rid of it?
Seller: Man. Trying to pay off my student loans. I'm so broke I turk when I get home from my full time. Can you help a girl out? 
Buyer: I know that feeling! So do I. I can offer you 165 if you are interested
Seller: Hmmmm. I don't think that seems fair. This thing has 165mm alloy w/ chainguard... I mean, who doesn't want that?! I can do $250. Someone else offered $250 but you seem like a really good person so I'd hold it for you. Even deliver it
Buyer: Well, I do really need this so I will do the 250.  I will just turk some more to make up the difference, thanks you got a deal.
Seller: You're the best. Rock on!
Seller: 
Buyer:
