When you jump on your bed, you expect that at some point of the jump, you'd come back down, only to jump again. The joy from jumping is the expectation that at some point, you'd recline back to the start and do the jump again, and you'd aim to jump higher and higher at every point.
But what if you just don't want to jump anymore, because you don't want to risk coming back down, you just want to stay up there and defy all the odds of gravity? Or you don't find this jumping game fun anymore, even if it is ultimately, a happy game.
