Staying Clean

The landlord is on his way over to show my apartment, and as a consequence I've spent an hour or two cleaning and tidying to a level that I don't normally achieve. And rather than my usual batch approach of cleaning things once every week or so (with the emphasis on the 'so'), I've been wiping down everything as soon as it gets messy. It's a very odd sensation, keeping things so clean. It's quite nice, actually, but I doubt that I could sustain it. And not quite sure why I'm bothering -- does it matter to me so much what the landlord and his visitors will think of the place?
