A small preference can matter greatly when larger choices are out of reach.

When most of a day is decided by other people, the remaining choices carry disproportionate weight. In a hospital, a care home, a job with no flexibility, or a childhood, which cup, which shirt, which side of the bed becomes one of the few places a person still gets a say. From outside it can look like fussiness about something trivial. From inside it is the difference between living somewhere and being processed there.

When someone in a constrained situation states a small preference, treat it as important rather than negotiable. Ask what they would like even when the answer changes almost nothing.
