I liken it to a bubble. They live in a bubble and get very upset when someone pokes it! They are happy to just be in this protected bubble and stay away from the influences of the world.
They do just turn their minds off when it comes to most things. They hear what they want to hear and that is all.
However, you have most definately planted seeds and don't think your wife won't remember what you said. She just doesn't want to explore the option of being wrong b/c this is all she knows. One doesn't know where to go from there b/c your whole life is the "truth" and you honestly haven't thought of anything beyond what you were taught!
Keep up the good work OTWO! After all, I bet there was a time when you thought you would never leave right? I never in a million years thought I would stray.
