I am also not a fan of the 'show home house' but I'm also not a fan on untidyness or dirtiness. I grew up in a home where things were clean and tidy but slightly cluttered. My bedroom was a sty, dirty, messy and downright unhygienic. When I had DD1 I became lazy in my own home from depression and it was a disgusting way to live. Now me, DH, and our two DD's try and live better.
The cupboards are a mess but the floor is hoovered, the windows and mirrors are clean, the toilet and sink are clean, the washing up gets done after every meal and the tops are wiped down and we do washing on a rota. We have family photos, ornaments, pictures in frames, candles, books, magazines and flowers around but we are tidy about it and try to make it aesthetically pleasing.
Drawing on walls is a no no. DD1 is 2.6 and her and DSS have a habit of drawing on the bedroom walls. Luckily we have them out of it now and the pens get taken away unless they're supervised but I have to paint over one wall in her room before the New Year now.
If I know I'm expecting guests I'll blitz. It'll take me 10 minutes. God forbid my Bampi comes. He hates it, calls me dirty, unclean etc and berates me. I try to ignore him now.
MIL has not dusted in a decade. Every surface is covered in washed/ironed clothes, knitting, knitting patterns, half finished craft projects, paperwork, school work, ornaments etc. It took me two visits to realise the thing the crap was piled on was a dining table. Complete with chairs you can't see/sit down on. She has no carpet in the halls or on the stairs and it has been that way for eight years. Their computer room is about 5ft wide and consists of enough space to squueze through to sit down and floor to ceiling shelves of books and board games.
Honestly, PIL's makes me uncomfortable.
