Charles M. Moore - Secret.

This is the secret
from long long ago
that's never been written
and never been told
a tale of the living
that's kept by the dead
these are the words
that have never been said

This is the story
that you musn't tell
by those who know nothing
forever to dwell
always kept hidden
and never revealed
in trust that is given
through lips that are sealed

This is the message
delivered in faith
vowed not repeated
in anger or haste
for once in the open
would make others weep
this is the sentence
you must never speak

This is the silence
that's passed on to you
with love it is given
though you always knew
from the beginning
deep down in your soul
that life wasn't quite
what appearances showed.

Charles M. Moore
