A : What is that, Jane?
B : Don't you know? It's my hamster. It's my favorite pet.
A : Oh! Really?
B : Min-ho, do you also have any pets?
A : No. In fact I don't like pets. They take too much time and they are expensive to keep, but my brother wants a pet.
B : What kind of pet does he want?
A : I think that he likes dogs. He thinks that they are loyal.
B : Yes, but they're also a lot of work. How about a cat? They don't take much work. Cats are the most popular pet in the States.
A : Cats? Well, I don't know.
