Sadness is the quiet wave of dark cold water as it hits the beach. Sadness is the fire that takes your soul. Sadness is a car as it drives away from an old house. Sadness is the dark night sky and stars shining above you. Sadness has come.
Silence is fireflies as they dance their warm summers night away.
Silence is wind gusting across the open plain. Silence is lightening streaking the gray sky. Silence is fat snowflakes swirling down to blanket the world. Silence is me watchng bright twinkling stars illuminate the ebony sky. So, in the second poem, the abstraction was silence.
