(A-hui comes home from work and sees his mother standing at the door.)

A-hui: Hey, Mom. You look worried. Anything wrong?

Mrs. Liu: Your sister hasn't come back yet. She never comes home later than five-thirty.

A-hui: It's ten to six now. Did you call the school?

Mrs. Liu: I did. They said Mei-ling left at four-thirty.

A-hui: How about her classmates? We should call them.

Mrs. Liu: I've called five of them, and they all have no idea where she is.

A-hui: Let me get my bicycle. I'll ride around and look for her.

Mrs. Liu: Aren't you going to have dinner with your girlfriend tonight? You might be late.

A-hui: Don't worry, Mom. I'll call her later. It's more important to find Mei-ling. Why don't you go inside and wait? Mei-ling might call home at any time.

Mrs. Liu: You're right, and I should call more of her classmates. Ride carefully, OK?

A-hui: I will, Mom.
