It is an extreme disorder.
Blanket randomly folded per sofa, mismatched but fluffy pillows, the crowd in front of the TV, slippers that you know will come from the owner randomly standing in the hall, drawings of preschool children taped to the walls, and even pencil/paint marks on the walls, a completely symmetrical curtain that was not drawn, in short, one would worry about oneself to get away from other unrest. It is the details that consist of things that are not actually a problem.
