There is no uncertainty about her waiting, for we know that she is waiting. There is only uncertainty about its outcome. Silence is lost, is loss. She becomes agitated as those sounds erupt and surround her. Her beating heart mistaken for the purring engine of an approaching car.
Desire is audible.
Perhaps the stranger is arriving. Her heart beats that little bit faster. There is, as Cixous reminds us, a law of silence. This silence not only veils, but secrets. In the case of the veil, which muffles rather than silences, the silence must be lifted and in the case of the secret, the silence must be kept.
