This thread really resonates with me.
I grew up with 2 fairly well adjusted professional parents in a nice house. It wasn't cluttered etc but it was always very dirty. Washing up never done and piled high, surfaces never wiped and ants crawling, floors sticky, sheets on beds for weeks and weeks, clothes never washed, bathrooms never ever cleaned. We didn't have any bins - I thought it was normal to put piles of rubbish on the floor or if we were lucky, into a plastic bag. We didn't have laundry bins, laundry was just chucked on the floor in the pile in communal areas and left there smelling for weeks.
I regularly had no underwear as it was all dirty and told to wear dirty pairs off the washing pile on the floor. I often had no clean clothes and had to keep rewearing (in fact I had really bad back acne but when I left home and could control my own washing, it completely cleared up). I couldn't bring friends home as they said it smelt and it was too embarrassing.
The state of the house was used as a weapon by my parents so me and my siblings were always shouted out for making the mess (even though we were little and it was more adult mess than child toy mess really). Regularly I would be dragged out of bed at 9/10pm because they'd suddenly decided the house was a tip, it was all our fault and we needed to clean. Horrific.
As a teenage I ended up doing a lot of cleaning just so I didn't feel sick about using the toilet etc which was always covered in mess. I remember bringing boyfriends to stay as a younger adult and the bed sheets being filthy and obviously used by multiple people beforehand. The shame.
It's made me feel very anxious and suspicious about other people's cleaning (and more the respect for people coming in to the home if that makes sense) when I stay anywhere as I assume no one has changed sheets or cleaned toilets and I really struggle to not freak out. I basically assume everyone is the same as my parents. I also feel really angry that they couldn't get their shit together and just do a bit of cleaning.
My house is pretty clean and tidy but not crazy so. We have a cleaner. I'm very particular about my children having enough clean clothes, that they are ironed and smell nice, that we use proper bins and laundry baskets and the house is nice enough to always welcome someone in. The shame lasts a lifetime though. I also can't imagine doing to my children what was done to me.
