"...In reading about Williams' life I was glad to find a
glimmer of hope. It turns out that as a child his
favorite book was C.S.Lewis' The Lion, The Witch and
The Wardrobe ,
He told how he would read the book to his own
children:
"I would read the whole C.S. Lewis series out loud to
my kids. I was once reading to Zelda, and she said
'Don't do any voices. Just read it as yourself.' So I did,
I just read it straight, and she said 'That's better.'"..."
