What you can’t know;

You can’t know for sure
Where I have been
What I have done
And seen and spoke
You can’t know for sure
What it is I believe
Or why I am sad
And what brings me joy
You can’t know for sure
Why I say what I do
Look towards the ground
Or deep in your eyes
But what you can know
Is that behind all the flaws
A skeleton lives
Until the day that it dies
