Hello, this is Mary speaking. Who's that?
It's me, Peter.
Oh, hello, Peter, whom do you want to speak to?
Can I speak to John?
No, you can't speak to him now.
Isn't he in right now?
Yes, he is in, but he is very busy.
What is he doing, may I know?
He is getting ready for school. Grandmother is combing his hair. Sister is looking for his coat. Mother is putting textbooks into his schoolbag. Goodbye, I've got to go now. I am holding the door open. The school bus is coming.
In that case, I'll ring him again this afternoon. Bye.
