I've had an experience similar to that :(
At least this house is okay after a bit of attention. Two years ago I shared a house with three people who didn't understand the concept of cleaning, I never want to see someone using a broom on kitchen surfaces again (and that was after moving off all the moldy plates/rotting food).
