Why is it that most people, when discussing a hypothetical situation, say, "...worst case scenario" instead of "worst case scene/ situation/ circumstance" etc? Do we really attribute disasters to the Italians? ;-)
Because that is one of the meanings of scenario. From Dictionary.com:
quote:An outline or model of an expected or supposed sequence of events: “In the scenario posed by many climatologists, decades of continued global warming would raise sea levels anywhere from 20 inches to more than 11 feet” (San Francisco Chronicle).
Build a man a fire and he's warm for a day. Set a man on fire and he's warm for the rest of his life.
