Jack: Imagine a man walking down a street underneath the street lamps. Right under a lamp, is shadow is the densest but also the tiniest. Then, when he starts to move, his shadow grows in front of him. The shadow becomes bigger and bigger while it thins out. And the shadow behind him from the next lamp post emerges and becomes shorter and shorter until it reaches its ultimate density, as the man stands directly underneath the light. Let's say that the man standing underneath the first lamp post is me when I've just committed a murder. I feel strong and content. I start to walk, and the shadow in front of me grows bigger, like my pleasure. But at the same time, pain is on its way, represented by the shadow behind me from the next lamp post. And at the midpoint between the lamp posts, the pain is so great it outweighs my pleasure. And with every step forward, pleasure dissolves and pain intensifies behind me. Finally, the pain is so unbearably intense that I have to act. So when I reach the point with the next lamp in zenith, I will kill again. Verge: I know you want to be someone special, Jack, but let's face it, this illustration can be used for any addict's tale of woe. The alcoholic empties the bottle at the zenith etc, etc. But what about the family?
