Input: Buyer: Hi! Can you tell me more about this bike? How old is it?
Seller: This bike is only two years old. A very sturdy bike constructed from steel. Also it is only slightly used as my child who I orignally bought it for hit a growth spurt shortly after.
Buyer: Does it have any issues? Flat tires, faulty brakes etc?
Seller: No there are no such issues I had sprayed the exposed metal parts with anti rust. Therefore the brakes still function smoothly. As for tires I had recently ensured to inflate back to the appropriate tire pressure.
Buyer: Would you take $70
Seller: That would be a little too low for me. Ihad previoulsy paid around 200 for it brand new so 70 would put me at quite a loss. I could throw in a bicyle bell if that would intrest you.
Buyer: What about $80 and I'll pick it up?
Seller: Would you still want the bell in this case?
Buyer: No.
Seller: Then that would be fine I could also meet you half way if necessary.
Buyer: Perfect
Buyer:

Output:
bike
