I hate that, too, for the exact same reason... and also because I'm a bit of a slob and my place is generally in a perpetual state of chaos... if my family comes to visit, I either have to clean up before they get ehre or they WILL start cleaning without my authorization.
Funny thing is, I know where everything is in my chaos, but as soon as my mum "tidies up", I lose sight of stuff, some times for months. And asking her where she put them is no use. She basically hides stuff out of sight, so she never remembers where she put things. -_-
