Well said Astrid - Lori you are a legend if you can keep up. I am guilty of being motivated the first few days and then everything gets forgotten.
But I have found just by doing a few little things each day helps to prevent the inevitable...

I totally don't iron at all. (Maybe once a year). I just make sure the clothes are hung right. And sheets? Why?? That lady maybe should of thought to clear up the mess first, because guests aren't going straight to your linen cupboard to see if you have wrinkles on your fitted sheet sets - GOD!

I too have a friend like that - everytime I go to her house, I feel so antsy - I just want to start picking stuff up, and vacuuming - her house really, really is bad. I just don't understand how people can live like that - like, this is dirty, and unhygenic, and filty... Even my 2 year old started clearing up when we went over last time! She started picking all the toys up, and making a pile of dirty washing - now that's getting picky!
