If a building has only two floors, an elevator only ever has one travel option (to the floor opposite the current one), so why even bring the numbers “1” and “2” into it? Not to mention that the “Close” button never responds, “Open” is pointless – ARGH!
In Alice’s world, “the books would be nothing but pictures,” and in mine, elevators in two-story buildings would have no buttons at all. When passengers stepped in, the doors would close, the elevator would move to the opposite floor, and the doors would again open. I can see a case for keeping the button marked “Alarm”. Maybe.
