21. A: What happened to your car?
B: I got a dent in the parking lot.
A: How did you get it?

A: Those shopping carts are dangerous.
B: Especially the metal ones.
A: I don't park at a store that uses metal shopping carts.
B: That's a good idea, but there was a good sale at this store.
A: Did you save any money on the sale?
B: Yes, I did. I saved about $50.
A: That's great.
