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. I am far from being a gifted teacher, by the way. I make too many mistakes. I don't monkey around with decoding.
