Have a look at the following transcript of Kiso-eigo2 Lesson 14.
One of the main character Ayumi came home, and her grandma was there.
A: Hi, Grandma! I'm hungry!
G: Wash your hands. Rinse your mouth, too.
A: Oh, Grandma... OK, OK. Can I have a snack?
G: No! Wait until dinner.
A: But Grandma....
G: Finish your homework before dinner!
A: Grandma... I'm hungry now.
G: Then drink some water!

She must be a spreme commander in that house. (^□^;)
