I was helping a friend of mine (who had to be in two places at once) by doing his march-out with the Housing person ...
And so, things got off to a rough start (i.e. "What do you mean he's not here?" huffed the Housing Thing indignantly ...)
We start doing the usual chicken poop type of inspection, but my friend was a very experienced old-timer and knew many of the tricks(i.e. hire one of the cleaners recommended by Housing, since they're all buddy-buddy with each other ...) - as a result, things weren't going too badly ... but then ...
The Housing Creature looks at one of the windows, and crows in delight: "These haven't been cleaned properly - they'll have to be done again!"
Fortunately, I'd had a quick look around beforehand, and I can tell the difference between dirt and ... rotted wood ... so I just played dumb, and said "What dirt?" in order to get the Housing Ogre to bend over closer to the offending window frame ... at which point I poked a finger right through the rotted wood all the way through to the outdoors, and innocently observed "I'll scrub it again, if you like, but I'll probably need some gun tape to keep the window from falling out ...".
And so, the marching out inspection was completed, and new windows were ordered for the next inhabitant (since my friend had repeatedly reported these windows as needing replacement ... but they'd ignored him).
