ABSTRACT
Picture the following scene: Footsteps leading up to a darkened door. There is a sense of unease in the air, a sense that something is wrong or out of place. A hand with a key reaches for the lock, only to find that the door is already open, although only slightly ajar. Hesitantly, the hand with the key pushes the door open and there is a pause for breath, listening for some sign that whoever might have opened the door is still there. However, there is no noise above the heartbeat of the individual at the door. With great hesitancy the door is pushed open and a step inside is taken. Another pause is taken to listen. There is no noise. The hand with the key reaches out and flips the light switch and suddenly the room beyond is flooded with light.
