"Some days are just bad days, that's all. You have to experience sadness to know..."

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

"Tears are words that need to be written."

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

"Sadness flies away on the wings of time."

"Sadness is but a wall between two gardens."

"The good times of today are the sad thoughts of tomorrow."

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