Pretending differs from passing and performing by its spontaneity

Evidence

To play the game, one may or may not plan to do so ahead of time (in contrast to both passing and performing which involve rather careful planning). Often, the opportunity to play “just happens” but even when it does, the individual is under no particular obligation to take advantage of it. And since the game is always played with strangers and always in public space, one can often, if things go poorly, simply leave the scene. — Lyn H.
