Alright, Sara, we know that you are planning something big for John's birthday. Could you tell us just what you have in your mind?
I want to make his birthday a very special event. John has a sister living in France. And I'll send her a plane ticket, so that she can be here for his birthday.
Boy! What an excellent plan! That's something special. I kind of guessed you had some secret plan and were waiting for the right time to tell me.
Well, I didn't want to say anything until I was sure she could come.
