"There is no greater sorrow than to recall in misery the time when we were happy."

"The walls we build around us to keep sadness out also keeps out the joy."

"It is sad not to love, but it is much sadder not to be able to love."

"Sadness flies away on the wings of time."

"You cannot protect yourself from sadness without protecting yourself from happin..."

"Behind every sweet smile, there is a bitter sadness that no one can ever see and..."

"Sadness is but a wall between two gardens."

"The word "happy" would lose its meaning if it were not balanced by sadness."
