Yes indeed, silence is a great strength and comforter.

"don't cast your pearls in front of swine". As they will turn and eat you up.
To me it means to take care who you share your personal self with and we see the results so often in the media.
A veritable truth that so many disregard and it returns with a vengeance to haunt them.

You certainly know what it's all about and even a lonely road in life is better than to be cluttered by the "swine".
