One dish in the sink is nothing. One dish is also how the tower starts.

A single item left out is genuinely trivial. What makes it worth noticing is that it changes the standard of the room, and the next person, including you an hour later, is deciding against a slightly lower bar. Disorder does not build from one large collapse; it builds from a series of reasonable exceptions.

Handle the first one rather than the pile. When you catch yourself making the small exception, spend the thirty seconds right then, and the tower never gets a foundation.
