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.
