P.L. Travers: My point is that, unlike yourself, Mary Poppins is the very enemy of whimsy and sentiment. She's truthful. She doesn't sugarcoat the darkness in the world that these children will eventually, inevitably come to know. She prepares them for it. She deals in honesty. One must clean one's room, it will magically do it by itself! This entire script is flim-flam! Where is its heart? Where is its reality? Where... is the gravitas?
[She throws the script out the window]
