A: Hi! Is there a specific car you're looking for?
B: I'm looking for a convertible.
A: We have a wide selection right here.
B: I don't see what I want here.
A: Really? We have over 100 convertibles.
B: I'm interested in a purple convertible.
A: That's a rare color in any car dealer.
B: I guess I have to go elsewhere.
A: Don't go! We have colors close to purple!
B: Like what exactly?
A: We have blue cars.
B: Blue is blue. Purple is purple. Good-bye.
