Observation
Systems run on people who show up even when nobody watches.
A mail carrier in Los Angeles learns something most of us never have to know: that the invisible infrastructure of modern life depends entirely on bodies that absorb the actual cost of reliability. Nobody needs to enforce John Ayala's route. Weather, aggressive dogs, the simple fact that the neighborhood expects him at the same time on the same day every day — that's enough. The mechanism is older than markets. We call it duty, or habit, or just how things work. But what it really is, is a deal where one party's consistency becomes invisible precisely because it works.
