The thing I like to explain to people who are learning to fly is, I tell them that the trainer planes we fly today fly well without much of a need for our imput. Many years ago when dinosaurs roamed the Earth, I had the problem with being rough with the controls with the full scale planes. My instuctor just reminded me to treat her like a lady and make the imputs light and smooth and watch what the airplane does and react accordingly. He said that often and it stuck in my head like the " Wings Level, Nose level to horizon!" bit.
I would invite the begginer over to your house and have him get some simulator time in. Then I think he would fair better when you take him out for the real training.
Just my idea that worked for me, I figured I'd give it a shot in telling you incase you wanted to try it.
