Its a Poem that has a deep meaning, that an individual who usually reads between the lines will quickly realize the true meaning of this poem.
For instance the lines;
I ask them to take a poem and hold it up to the light like a color slide;
this simply means to take a closer look, beyond the written words and understand the actual words within before reaching a incomplete conclusion.
Also the line where it says, But all they want to do is tie the poem to a chair with rope and torture a confession ou of it. this again is another hint, that shows humans in general want to cross the finish line before getting to the starting line and again it emphasizes on patience in order to reach the true goal of any challenge we may face in life.
