Begin with 2 players,
each on a chair. In character they start to talk
about what happened to them in the past. Players take turns talking.
Then follows a series of scenes, and for every new scene location the chairs
are moved. When returning to a scene location played before, return the
chairs to the position they were in in the original scene in that location.
End with the 2 chairs back front stage, as in the beginning of the play.
At the same time (of course) conclude the whole story.
Usually played with 2 players, but more is possible.
