Poetry?

What makes a poem a poem?
I could argue anything is a poem.
My words which I spit from my pursed lips
Take their place in the world.
Significant?
Maybe not.
But then again
my words may crash upon the world
becoming a surging tidal wave
and destroy all that is now
and create place for new.

letter after letter
I plant the seeds
shaping words
which in turn
burst into bloom
ever changing this world.
forming this.
A poem.
