　　Sarah: What are you doing on your mobile? Sending a message?

　　Mary: No, I’m counting calories.

　　Sarah: What? Why are you being so health conscious?

　　Mary: I’m growing a lot. I want to keep my body healthy.

　　Sarah: How do you do that?

　　Mary: Well, first, I am careful about what I eat.

　　Sarah: What about KFC and McDonald’s?

　　Mary: No, that is not considered being healthy.

　　Sarah: Okay, so what next?

　　Mary: Then I use the calculator on my mobile to keep track of my calories.

　　Sarah: Yes, a growing girl needs about 2000 calories a day.

　　Mary: I am eating a piece of bread so that is 100 calories.

　　Sarah: Wow! What a good idea.
