Jason: Alice, what’s your favourite pet?

Alice: I like cats best.

Jason: Why?

Alice: Well, cats are pleasant to hold and to touch.

Jason: But cats just lie around. They don’t do anything. 

Alice: Oh, my cat likes to play. My cat even catches mice.

Jason: And then, cats just do as they wish.

Alice: That’s true, and that’s one of the things I like about cats. They don’t need people. They can be kept more easily than dogs. Dogs need a lot of attention, and they bark noisily.

Jason: I see.

Alice: What about you, Jason? What’s your favourite pet?

Jason: I like fish.

Alice: Fish? Why do you like fish?

Jason: They’re easy to take care of.

Alice: But you can’t play with a fish or even hold it.

Jason: True.

Alice: In fact, you can’t really do anything with a fish, except watch it.

Jason: That’s what I like best. I don’t really have time to take care of a dog or cat. At the same time, it’s nice to watch the fish swim around.
