Much to be said- silence

there is much to be said of silence...
it is more than a stillness of air,
there is less to be said about laughter
even laughter laden with care.
silence can bind, destroy and rebuild,
a century in a blink.
more words can be said in the silence
than could ever be said in a week.
the silence is charged,
as hand to hand we touch.
the silence can be angry,
heightened by a livid blush.
the silence is louder than shouting,
the silence is lighter than air,
the silence, the silence, echos,
echos the unsaid dare.
there is much to be said of silence,
the wises of us know,
there is much to be said of silence,
so,
why does it hurt us so?
