__________________ RC50 As you come into this world, something else is also born. You begin your life, and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow — never faster, never slower, always coming. You will run, it will walk. You will rest, it will not. One day, you will linger in the same place too long — you will sit too still, or sleep too deep. And when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.
