There's a scene in (Roald Dahl's) "Matilda" in which Miss Honey sees that Matilda's seat is empty. She pantomimes to another student (Where's Matilda) and gets the pantomime response (In the Chokey!)
When the Trunchbull asks her a question, she only responds with a nod, and exits the room. This arouses the Trunchbull's suspicion, but the significance is that Miss Honey has stayed in the non-verbal communication mode for the scene. It's interesting, and it plays in my head when someone is voiceless.
There’s a musical of “Matilda.” I’ve heard some of the songs on the Sirius Broadway channel.
