You forgot the most likely outcome: (d automatically reject the story because it contains poetry.
Lemme guess. The scene from your story goes:
Shirley said, "What're you doing?"
"I'm reading a poem by W. H. Auden," Babs replied.
"Read it out loud."
[8-line stanza of poetry.]
"Enough," Shirley cried out. "Christ, no wonder poetry is a dead art form."
I went to the web to see how long Ezra Pound had been dead. My first stop was this site, where I clicked on the first poem which is called "A Girl." But instead of the poem I got a bitter rant from the site owner complaining that the Ezra Pound estate had asked him to remove the poem. I clicked on the second poem and got the same thing. Apparently this guy set up a site devoted to Ezra Pound's poems, and the site now has no poems. I predict he busts into the law offices of the Ezra Pound estate's lawyers any day now and blows everyone away with a sawed-off shotgun.
I then went to another site and found another list of Pound's poems. I clicked on "A Girl" and the poem appeared (here), along with three incredibly insightful comments. So apparently, either the Pound people are selective about which sites print their guy's poems, or they haven't found this site yet.
The poem, by the way, is about a girl turning into a tree. I think fair use rules allow me to print one line of it:
The branches grow out of me, like arms.
Heavy stuff. Maybe you should go with Edgar Allen Poe.
I think his stuff is in the public domain, and his stuff is for adults. Think about it.
You might also try what I recommend to people who want to use song lyrics:
write your own. For instance, here's a line of poetry you can use:
The chimney grows out of me, like a zit on my scalp.
That's from a poem I just wrote about a guy turning into a house.
You'll want to ascribe it to a poet. I recommend making up a name.
It should have three syllables, as the best American poets
(Robert Frost, Carl Sandburg, Ogden Nash, Ezra Pound) do.
Go with Prig Williams.
Another strategy is to worry about this after someone expresses
interest in buying the story.
