Food tastes bland without any condiment or topping,
No ketchup or mustard or even pickles in that burger,
Will make a burger just be a "burger".
Songs without rhythm are just plain out bad,
No beat to make you want to get up and go on dancing.
Will make a shout and stomp just be a "shout and stomp".
A novel is not interesting if it doesn't have a plot.
No story? Nothing to say other than "I remember that book" after finishing it.
Nothing at all.
Add something special to those things though,
That burger will be much more than just a "burger".
That song will make people do more than just a plain "shout and stomp".
That novel will have more than people just saying "I remember that book".
This is what poetry is.
Not something less than a satisfying taste of a well-made burger,
Not something more that will get a group of people to shout and stomp and create a riot.
Nothing at all is better than what poetry can and does to its audience.
The something special needed to intrigue everyone's attention.
