Picture yourself walking down the streets of a large city. It is night. You feel vulnerable, and the people of the night are doing various things wherever you go. Your heart beats intently as the dreariness of the city wedges itself in your solar plexus like a large splinter. Walking at a quicker pace, people whisper secret things to each other, make secret deals. Are you a target? Its only a matter of luck on these streets. Finally you see your destination, and you flit into the building, leaving the night behind you.
