Dr. Brent: "You know Mr. Nightshade, smoking isn't good for you. It causes all kinds of health problems and it's expensive. You really should try to stop smoking."
Mr. Nightshade: "Yeah, I know."
Next visit, a few months later.
Dr. Brent: "So Mr. Nightshade, how are you doing with smoking?"
Mr. Nightshade: "I quit."
Dr. rent: (rather shocked and dumbfounded) "Wow! That's great! What finally made you decide to stop smoking?"
Mr. Nightshade: "God told me to stop smoking."
Dr Brent: "Err, that's wonderful that you stopped smoking."
Next visit a few months later:
Dr. Brent: "So, Mr. Nightshade, how are you doing?"
Mr. Nightshade: "I'm fine, but I'm smoking again."
Dr. Brent: "Oh, why's that?"
Mr.Nightshade: "God told me to stop smoking, so I stopped smoking. But the more I thought about it, the madder I got. I like to smoke, so why should God tell me to stop smoking? It made me really mad. I wasn't going to let God tell me what I can and can't do, so I started smoking again and I told him to be quiet."
