Present flow chart — Your wife
Has she not been taking her position seriously?
After all, women should know their place...
It's not like they have to do anything difficult...
There after all some basics that she should have mastered by now...
Maybe it's an intellect thing...
After all you're smarter than her and she should be reminded of that. Constantly.
Maybe things would be better if she shared some of your hobbies? Under strict supervision of course.
Or maybe it's time to call it a day...
Are you just cheap and lazy and can't be bothered shopping?
