I think the angles created by light and dark are very striking because they create a strong sense of perspective and dimension whilst stripping away all colour. The light/dark takes away from the actual shape of the room and creates a new, unusual one.
You know that feeling you get when someone's behind you? I crave it. I.... it reminds me of you I suppose, the way you made me feel, your dark eyes filled with this... this instinct... I didn't know whether to run away or to fall into your arms. So follow me home. It's not fear that's making my heart beat faster. It's the memory of you.
