Mrs. Green: Hello, This is Mrs. Green. Who’s that?

Jim: Hi, Mum, this is Jim.

Mrs. Green: Oh, Jim. It’s seven o’clock, have you been at school?

Jim: Yes, Mum. We are having a dry run（排练） about our drama, so I will come home late. Please don’t wait me for dinner.

Mrs. Green: OK, please take care of yourself.

Jim: Take it easy. I’m not a little boy（我不是个小孩子了）. I have to go now. Bye, Mum.

Mrs. Green: Good bye.
