My parents house was, and is, a tip. When I was a child I would tidy and clean it, and mostly I'd be tolerated with little jokes, or told off (because I'd wasted resources cleaning something that didn't need to be cleaned, such as raw meat juice on the floor or mould in the fridge). Unfortunately, by the time I was in my teens, I was the only person who cleaned, and I still got told off for it - my mum would have a strop if I cleaned her fridge. So I'd do it all surreptitiously. The result is that now my parents are in their early 70s, it's an absolute pit.
I am much cleaner and tidier. I do sometimes disagree with my DP - she's very much from a 'shoes off' house and I will let DD onto the (washable) kitchen floor in her wellies; I might walk through the house in my fancy heels to pick up a forgotten bag or phone, knowing I don't wear my good shoes anywhere mucky and do clean them, so they won't be very dirty. OTOH I definitely have a 'robust' attitude to use-by and BBE dates, inherited from parents. I am very different from them, in that they thought you cut mould off then ate the item, or tolerated cream if it was just a bit sour. But I will eat some things that were use by yesterday if they look and smell fine.
My parents' standards really impacted on me as a child, and taught me how miserable life can be when you let things get on top of you. Even today, if my mum cooks a simple meal (and she's a good cook), it will mean grease, dropped food, boiled-over pans, all over the kitchen. It's hard to clear up. As a child I thought that's what cooking was. These days, even if I have a nice visit with them, I can't help breathing a sigh of relief to get back to my nice, clean home.
