-Good afternoon. Can I help you?
-Hello, I would like to buy a bike. (B)
-Sure, have you choose one, already? (A)
-Yes. I like the red one, with two-cylinders. How much does it coast?
-The red one? It cost - fourteen thousend dollars.
-Wow. That is too much for me. Do you have something cheaper?
-Well, sure. We have this great bike for just ten thousend dollars.
-Thank you, but I think it's too early for me to have a bike. Goodbye
-Good luck
