There are things that have a specific place where they're supposed to be. Nevermind that they spend 99% of their time someplace else. When you clean up, you know exactly where they go. Then when you get ready to drag them out and leave them on the coffee table for another six weeks you know where to find them. Why you don't just consider the coffee table their "home" instead of that nook in the bookshelf where they "belong" but rarely actually are is just one of those mysteries of human nature.

There's no way a stranger could ever deduce the correct place to put those types of things, and no way you'd ever find them if they were put in the wrong place. So, if you ever want to see them again, you have to put them where they "belong". Then, when the cleaning person leaves, you can put them back on the coffee table.
