It all seems so obvious after you look at the photo. We've already descended into an etiquette-less society underground, hellbent on disturbing one another with our bare feet, our nail clippings, our banana peels and our hanging brains. We already treat the subway like our personal toilet—so we can all learn something from this young woman, who re-contextualized her toilet plunger and put it to far better use in a Tokyo subway car. Her epiphany can be our salvation from pole huggers.
