Sit, Stand, Bend (Lie Down)

Three actors start on stage. At any point in the scene the actors must always be sitting, standing, or lying down. The catch is, there can never be more than one person in any of these three positions. For example, if an actor sits, then the actor that was previously sitting either needs to stand up or lie down. In addition, any actor that moves needs to justify why they did in a way that makes sense in the scene.
