Is this a good poem?Im only 13?

For being 13, this poem is typical. I disagree with those who said to change the phrase "your the cheese to my nachos" because it is original. The phrase "the boat to my oar," and one that someone suggested "the thorn to my rose," are cliche. You want to avoid cliches in poetry and make a phrase/poem your own. Be aware that not every poem has to have end rhyme, that's the joy of free verse. Also, remember that in poetry to "show; not tell."
