People say this all the time, my house is a mess but it's always clean but how? If your house is a mess then who knows what filth lurks under piles of papers or clothes or boxes. Anytime I've ever been in a messy house it has always been pretty dusty and unclean. Times when my house has been messy its much harder to actually clean, I need to tidy everything up and organise the space to get ot properly clean.
I mean it's fine if your house is messy and not cleaned because that's life we all have different tolerances of mess and dirt, we all have different circumstances but why say "my house is messy but clean" when it is so obviously not true?
