I think alot of people expect there wife's to be bad with mechanics or anything that might not be the "norm". So that is what they get. And then there are alot of women that have never been exposed to anything outside of the kitchen and household, so they prefer to leave well enough alone. And if that is how both like there relationship then there isn't a problem, and I think that is wonderful. My parents were like that, my dad did everything outside of the house, and my mother did her thing inside the house. Of coarse I was always there to help my father, and he had the attitude of "your mother is an idiot, leave her in the house". This kind of worked for them, but I always thought it was sad, when two people that love and live with each other, could not work together with a common goal and desire. Maybe that is what influenced me when I was dating, Or maybe I just didn't want that type of a relationship so I included my wife? What ever was the case, I am much happier for doing it . We do almost everything together, no she doesn't weld or cut metal. But she will help hold, lift,carry things, and with her small hands she is the one that gets to start that hard to reach nut, or retrieve that dropped wrench. I wish more people would include there spouses, we have built race cars together,atv's,and diesels. She might not know all the tech stuff, but she sure knows were it goes, what it does, and how much that piece cost. We also both enjoy cleaning and maintaining the stuff, and often find ourselves talking as we clean this or polish that, it is almost like a therapy session, no doc, but we get things ironed out.
