Defiance with a Smile

I say to Avi, "Get in the car and go directly to your seat and get in it. Do not go to the back of the car." It's very clear that he has heard me. What does he do? He gets in and goes to the backseat and puts on one of the belts. If this was the only time he did something like that in a day it wouldn't be such a big deal, or even five times, but how about a couple dozen times a day. Constant clear CLEAR communciation. Total and complete defiance in return all day long. It's defiance with a smile and plenty of laughter on his part, but it's defiance nonetheless.
