Where is it written where does it say, each poetic line must end in a rhyme?

Where is it written where does it say, each broken heart only bleeds in the dark?

Lost photographs, lost memories and no proof of you and me. Just a faded ticket stub from that show in New York City. Where you danced for money and walked away from me.

I wonder sometimes, how it could have been, but so much time has come and gone, empty power just like the invisible wind.

Life and death, they fall upon us just as the memories of youth and love fade away. Just as the streets after a rainfall always seem to dry, the pure white snow turns to black and melts away, just as the once promising dreams always tend to die.

I cannot remember your smile or the way you said goodbye, just a reimagined memory of a love lost in time.
