My mate lives in a house with a 'live in' landlady. She NEVER cleans the house! It is extremely dusty, dirty etc, everywhere! Rooms piled full of c r a p.
Cats bowl never cleaned out, mouldy cat food around bowl. Its disgusting there. He is trying to move out but nowt available.....
His room is the cleanest room in the house...
That sounds like hell to me. I hate dirty people !



Clean is clean up to a point of diminishing returns. Surface level day to day tidy with a periodical deep clean is reasonable but there comes a point where it leans into obsessively clean/ocd. And that my friends is a mental issue imo. 
My dogs have a bag full of 'Victims' aka dog toys they like to destroy and spread their fluffy innards all over the floor on a daily basis so we have our routine pretty much nailed.
