What does this rock know about my pain? Why do such things happen? A stone tumbles down a mountainside and the course of all things are changed. All things are independent yet are dependent on each other. One domino topples another which topples another. Paths intersect without warning. Some are in the wrong place at the wrong time and some are in the right place at the right time. There is no clock that can foretell what that time and place will be. The rock sits silently, all knowing.
