If your household is anything like mine, objects have a mysterious way of moving into the wrong rooms. Fix that constant problem by remembering ABC: Always be carrying.

Before you leave a room, check if there’s something that belongs somewhere else so you can grab it and move it.
I’m not sure where I heard this advice, but since learning it, I’ve always got something in my hands, tidying as I go. (And, yes, I know “carrying” has a different meaning when it comes to guns, but that’s not what we mean here.)
