Over the years, my DH and I have worked out a pretty good system--we each do what we do better than the other. I do all the housework, but he does all the yard work. We have a big enough yard with enough leaf dropping trees that this is equitable. I like the housework done a certain way (okay, MY way), so I'd end up redoing it if he tried. We split most other duties. I dothe dinner cooking and the dishes (I can make things that don't require a can opener). He manages a bike shop, so he does any bike maintenance beyond cleaning and changing flats.
