Get a new wife !
What is a wife doing telling you what to put in your garage !
My wife fully understands the rules which were not agreed to by force, it just common sense, I don't tell her what shade of Chartreuse to paint the living room and she does not tell me what goes in my garage.
She has never once asked (well she has but did not expect a answer) what to do in the house or where to move things or what color to paint, she did expect me to do the painting and/or moving of furniture but never asked for my opinion. And in return for her having her house, she never tells me my garage is dirty, needs something, etc. yet she helped me paint the walls/ceiling. Its HER house, MY garage, our yard since we do talk about things there like where to put the pizza oven.
Oh and today is 32 wonderful years with her (about 35 years if you count dating years) so it works well for us.
