I can't help much either. when I got married, way back when dirt was first invented, my wife and I divided up the responsibilities. She took all the big decisions and I took the small ones.
She decides what we are going to do about things like North Korea, nuclear non proliferation treaties, global worming,
Prince Harry's wedding etc.
I decide the little stuff like when I buy my truck and what kind and whether or not she is responsible and pleasant enough to be allowed to drive it.
We have 3 pickups. The no payment thing is awesome. We both drive with some common sense. I try to keep the maintenance up and for the most part we very seldom have anything major go wrong.
We LIKE driving out trucks and that is a big plus. My 2000 gmc has about 430,000 kms and I love driving it.
I had some front end work done recently and I'll touch up some paint this winter, but other than that she goes when I want it too,
