Blind emotion

What is this emotion
But a window, darkened so
Allowing others to see
But blinding you to yourself
While others see you clearly
You are barely hanging on
To a glimpse of what emotion
You are wearing
Others see the things you show
All your secrets trickle down
From your mind onto
The blank sheet of your face
Your countenance tells all
Blind emotion has no secrets
And you cannot guard the world
From what you feel
And there is no escaping
From emotions that you hide
For displaying them
Will only make them real.
