Most of my married life, there have been kids, and all their friends in the house, and scads of cats, dogs, bunnies, and even pet rats, and it was just fruitless, to try to keep everything in its place...so we have that 'lived in' look, and thats the way it is...
Several years ago, my husband went down to Florida, to visit his aunt and uncle who were ill and aging, and he wanted to spend time with them, before they got any worse...his aunt was a complete 'neat freak'...she could not stand to see a speck of dust anywhere, or any little speck of dirt anywhere, or a dirty cup in the sink...it drove her nuts...
And her constant cleaning, and picking up constantly behind everyone, made my husband nuts...But this aunt and uncle never had any children, nor every had any pets, so for the aunt, her house was a prominent part of hr life ...each to their own, I gues....
If my house was absolutely spic and span, and sparkling all over, and everything in its place, the hubby would figure either he was in the wrong house, or else I had hired some help...
I suspect, no matter what, he will just be glad to be home...vacation is always nice, but its just so true, 'Theres no Place Like Home'....
