I have a fortnightly cleaning lady, and usually the day before she arrives I'll give the house a bit of a tidy - putting away all DC's numerous toys, making sure we've not left clothes lying around the bedrooms or bathroom etc.
However, I happened to mention this to a friend and she said I'm crazy as what's the point of a cleaner if I'm cleaning too? But surely I'm not that unusual? I'd rather my cleaner had more time to do the stuff I don't do like scrubbing and mopping than tidying away toys!
