There's something apparently intimate, endearing about a lost voice. To small children it is, evidently, magical. They lean in close and tell you things as though they were divulging, not just answering simple questions.
Would you like a sticker?
What are you going to do with it?
I'm going to put it on my jacket.
Imagine this whispered with hands cupping a little mouth to prevent anyone outside the conversation from seeing what is being said.
How did you lose your voice? Were you iceskating?
Are you sad?
Will your voice ever come back?
