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.

Seller:

Output:
bike
