Is Lewis Picking Up on the Injunction in the Gospels?

There's a line which says, shaster had a fixed habit of never telling grown ups anything. If he could help it, he thought they would always spoil or stop whatever you were trying to do. I think what lewis is really doing is just saying, don't judge by appearances. Younow, there's depth to animals, as depth to children, and let's be respectful of this.
