Your eyes are open to the rest of the world, Seeing all that await you.
You see the passing of time but blink,  unaware that you miss the best moment.  You finish looking at the world behind the glass and find it stained black and colorless.  You now know that the grey world behind the glass was a lie and you found the truth.  Was it worth breaking out of your cage?  Or would go back to looking through your colorful glass?
