You Say

You say,
That he's
Slowly drifting away,
But really,
I am;

You see,
He disappears
Fading away,
But really,
I am;

You sense,
That he's
Withdrawn,
But really,
I am;

You say
You sense
He's fading,
But really,
I am;

You see
Me, so I can't
Be drifting?
But really,
I am;

You sense
Happiness, so I can't
Be fading?
But really,
I am;

You can't see
The silent screams,
The pale me,
The true lies,
You can't;

You can't sense
The hidden shield,
The agony,
The enduring torture,
You can't;

You can't,
You won't
Notice me,
He's drifting away,
You say;

But really,
That's me,
Silently screaming,
Silently drifting
Away;
