Clutter can often create friction in a relationship—yet when couples manage to see eye to eye on their clutter issues, Peter says it can make the difference between living in a domestic war zone and living happily ever after. "When that's the basis of discussion—'your stuff or my stuff'—there has to be a winner and a loser in that discussion," Peter says. "Whereas if it can be shifted slightly so that it's, 'What's best for us,' it's not about winners and losers—it's about the outcome."

Peter talks with two couples about the clutter conflicts in their relationships, as well as the steps they took to solve them. He also speaks with a caller who has been married 24 years about ways to eliminate the emotional clutter that can build up between two people.

Peter also talks with professional clutter expert Joyce Dorny, a mother of six and the editor-in-chief of Organize magazine. Joyce talks about the negative effect that clutter can have on couples, as well as the great rewards for the entire family when things are neat, tidy and under control.
