How can I spend time away from my wife?

Although this is probably not a conscious question we ask ourselves, I'm sure it's a question we answer with our actions. Why is it that we feel we've earned the right to vegetate on the couch after a days work while our wives have been up to their proverbial elbows in "housework." I bet there's only a few of us out there that really knows what that means; "housework." For my family that means laundry and lots of it; cleaning up after 3 young children, (you'd be surprised at the speed with which small children can make messes); doing the dishes; washing the kitchen table; washing the floor; etc. Now, this is all in 1 day's work! What do I do? Sit on my ass all day, & type on a computer.
