I work in a building with two floors.
There is an elevator. When you walk into the elevator, there are two buttons to select your destination: First Floor and Second Floor. Think about this for a second....
Why not put in a single button that says "Go" or "The other floor" or even "Take me where I am not" - then let the elevator figure out what to do with this command.
