It had been done by me(or us)

You could be my unintended
Choice to live
my life extended
You could be the one
I'll always love

You could be the one
who listens
To my deepest inquisitions
You could be the one
I'll always love

I'll be there
as soon as I can
But i'm busy mending broken
Pieces of the life
i had before

First there was the one
who challenged
All my dreams and
all my balance
She could never be
as good as you

You could be my unintended
Choice to live
my life extended
You should be the one
I'll always love

I'll be there
as soon as i can
But i'm busy mending broken
Pieces of the life
i had before

I'll be there
as soon as i can
But i'm busy mending broken
Pieces of the life
i had before
Before you

A very very old tale. 

That's enough.
