From a distance, the sound of a bathroom door creaks open, its off-axis swing causing a slight judder. This is no ordinary door, but the entrance to a shower. It's an echoey, resonant sound as the door swings wider, the rattle of metal on metal evident as if the hinges are slightly loose. Its motion seems to fill the air, the sound reverberating off the bathroom tiles. The door finally reaches its full arc, the noise subsiding to a gentle whisper, leaving behind the quiet ambiance of an open, vacant shower.
