Example Input: Buyer: Hey, nice bike you have here
Seller: Thank you! Are you interested in buying the bike?
Buyer: Can you tell me more about it? It'd be nice to ride down the boulevard during summer.
Seller: Yes, this bike is perfect for long bike rides. The seat is memory foam, so you won't have to worry about pain. The 7 speeds will allow you to customize your speed, whichever suits you the best. I just replaced the tires, so those are in great condition! And there is not a scratch in sight! 
Buyer: I really like that, sounds like you keep it in tip-top shape. My budget is in the range of 50-60, does this sounds reasonable to you?
Seller: I will accept $60, because I feel like you will really enjoy this bike as much as I did.
Buyer: I'll give you 65, you're a good person.
Buyer: 
Seller: 

Example Output: bike

Example Input: Buyer: I am interested in your bike. Is there anything wrong with it?
Seller: It does need new handlebar tape and maybe tires.
Buyer: Okay, is the price negotiable?
Seller: A little, make me an offer.
Buyer: I have looked up what this bike is worth and taken into account the new handlebar tape and tires and I would feel comfortable paying $700, would that work.
Seller: That is a little low, I understand it needs some things. I would drop the priced to $1,000.
Buyer: I just can't pay that much, it isn't worth it. How about $775?
Seller: If you can pick it up today and pay cash I would take $850.
Buyer: I just checked and I have $836 cash, if I am there today and pay cash would you take that?
Seller: Yes, I suppose. Please make it over earlier rather than later.

Buyer: 

Example Output: bike

Example Input: Buyer: Great bike. Is it still available?
Seller: Hey man! Yeah it is! I am pretty sad I have to sell it. 
Buyer: I'm really interested but I'm short on cash. I've got about $1100 saved up if you would take that
Seller: I understand that you are short on cash, that is another reason I am selling it myself. What about 1400? 
Buyer: $1400 is too high for me. I can probably swing $1200?
Seller: I really put a lot of money and word on this. I tell ya what I will go as low as 1300. I really need the money right now and that is as low as I can do. What do you say?
Seller:
