Buyer: Hi! I am interested in your bike. How long have you had it?
Seller: I'm glad you're interested. We've only had it for about 6 months. It only has about 50 miles on it!
Buyer: That's definitely a plus! My wife is an avid biker and I want to surprise her with a nice bike. Something like this would normally be way out of my price range. But, I figured I would give it a try.
Seller: Well my wife has definitely enjoyed it, so if yours is like mine I'm sure she will too! I've listed this at $1100 and I expect it to go quickly.
Buyer: I won't argue that it is a decent price. Just wondering, is there anything wrong with it? Seems like a lot to spend on a bike that only has 50 miles of usage...
Seller: I'm not aware of anything wrong with it - unless you count the fact that it's taking up space in my garage that I'd like to use for other things!
Buyer: Well, I would love to take it off of your hands at $800. I'll throw in a birthday party invite. lol
Seller: If you can make it $900 and pick it up today, I think we can make a deal
Buyer: $900. I think we have a deal!
Seller: Fantastic!
Seller:

Output:
