Kai greets his parents with a sad and anxious face.

Mother: "Kai, we've been waiting for you. We thought you'd never come home. What took you so long?"

Father: "You didn't do the chores your mother asked you to do? Again? How many times have we told you that you need to be responsible and do the things you're supposed to do? You're not a child anymore, Kai. You're 16 now. It's time to grow up and act like an adult."
