theories of cleaning

Okay, I've come to the conclusion that at my house there are three types of cleaning: kid clean, which is everything jammed into the closet, in a bin, or under the bed with no sense of rhyme or reason and is good enough for them; mom clean, which takes the time to actually put things in their place and allows the occasional luxury of sitting down without feeling guilt; then there's mother-in-law clean, in which every nook and cranny is explored and scrubbed and everywhere one turns there is another corner to expunge of filth! I got to do a bit of the last one yesterday, and now that Mark's mom is here, I'm turning every which way and seeing something that I should clean better.
