Maybe, Yes or No

His response was harsh but simple,
Edgy N and rounded O.
Oh my darling heart, oh my wasted hope!
But then, after a few breaths of silence,
He kept on talking.
And in his words, there was a hidden song.

It said:
My edgy N and rounded O
Perhaps it's hard to take
But easy to let go.
You are the mountain river that has the power
To determine its own flow.
The flow that's  complex yet much stronger
Than my Maybe, Yes or No.
