Disorder becomes normal when it grows slowly enough.

Standards move quietly. A little more clutter, a slightly later start, a bit more tension in the house, each increment small enough that nothing seems to have changed, until the current state would have been unacceptable a year ago. The slowness is what defeats perception. You cannot notice a gradient by looking at it.

Compare your current situation with a photograph, a record, or a memory from a year or two back. The gap is often surprising. Periodic comparison is the only reliable way to see slow drift.
