A Rose, One Petal Fallen

What is this here?
Calm, Serene
Never has seen the light of day.
Never glimpsed a beautiful past.
It went by too fast to pray.

For a chance to give
A chance to earn
A chance to taste morning dew
A chance to follow when we can accept
That not all dreams come true.

This object here
So sad and beautiful
I sometimes hear it calling
It is a flower, old and wise
It's a rose, one petal fallen.
