F: Oh, what a beautiful cat! What do you think? ,M: I think I'd rather get a dog. Dogs are more faithful than cats. ,F: Yes, but there so much work. Would you be willing to walk it every single day and clean up after it? ,M: We'd have to invest a lot of money in a cage or a fish tank, and I don't really know how to take care of a bird or a fish. ,F: well. We're obviously not ready to get a pet yet.

Keeping a fish costs a lot of money and maybe it's not worth to spend that much.
