This is the original 'the Oak and the Rose' by Shel Silverstein
An oak tree and a rosebush grew,
Young and green together,
...
With their sparkling beauty,
they fall down to Earth as lonely tears.
Millions by millions, they cuddle together.
As if best friends, known forever,
...
It is reflected off the human heart,
Piercing the world like a dangerous dart.
It won’t be gone with us humans about.
It’s just so sad for the victims, no doubt.
...
All the happiness has left,
the dream is now gone.
There’s no motive or reason,
it was merely withdrawn.
...
