We all know them. They are The Clean People. Every time you go to their house, is is pristine, and when they apologize for that one stray sock on the floor, you feel a murderous rage bubbling deep inside you. You may think the Clean People come from another race, but the truth is that Clean People are not superhuman. They just happen to know a fundamental secret of decluttering: to keep your house from feeling crowded, leave out a few things that you really love and stash the rest.
