" The central attitudes driving the Drill Sergeant are:
I need to control your every move or you will do it wrong.
I know the exact way that everything should be done.
You shouldn’t have anyone else — or any thing else — in your life besides me.
I am going to watch you like a hawk to keep you from developing strength or independence.
I love you more than anyone in the world, but you disgust me. (!!) "
