^ I can sympathise.
I just finished Spring Cleaning my place yesterday. It was a multi-day job, spending a couple of hours each day. It's all sparkly and clean now. I cleaned everything, even behind stuff that hadn't been moved since I moved in about 7 years ago. And probably not since the whole building was completely renovated about 10+ years ago. Seriously, Monica Geller would be pleased with the flat now. Well, almost. I really can't be bothered to properly scrub the kitchen floor, so a mopping will just have to do there.
It's both satisfying, but depressing, because I know a regular clean at least will need doing again soon. A friend recently got in "a lady who does" who does a great job; I reckon I might just poach her to do a few hours at my place every fortnight.
