Tragedies show how important your life is to others; how fragile, and yet how amazing life is. You cannot imagine no life, because without life, there is no logic, no chaos, no love, no hate, no experiences. No mistakes. No memories. Nobody. Nowhere. Nothing.
However, you must cherish it, for you only have one; enjoy it, for this is your only time to do so. Live. Love. Learn. Remember --- Always.
