【正确答案】：
     LIFE IS NEITHER FILLED WITH JOY ONLY, NOR ONLY FULL OF SORROW. THEY OFTEN GO HAND IN HAND AND COMPLEMENT EACH OTHER.  
     JOY IS LIKE A FLUFFY LIGHT CLOUD WHILE SORROW AN OMINOUS DARK ONE. THESE TWO KINDS OF CLOUDS OVERLAP IN THE SKY OF LIFE WHICH , AS THE SUN IS SETTING , MAKES A STRIKINGLY LUMINOUS DUSK.
     AS YOUR LIFE COMES TO THE TIME WHEN DUSK IS DRAWING NEAR, THE ROSY SETTING CLOUDS MAY BRING ON A FEELING OF NOSTALGIA, OR EVEN MELANCHOLY. THE HUMAN SOUL, HOWEVER, REMAINS EVERLASTING; THE EARTH SPINS ON ITS AXIS AND JOURNEYS AROUND THE SUN ALL THE TIME.
