I think this is really excellent. I think if you separated out the last three lines of the first stanza into a new individual stanza that would be extremely strong. I read the poem three times and when I read it aloud in that way it was REALLy effective. Also i do not think i would say 'highly unlikely' - it does not quite fit right with the strength of the rest of the poem- I would just say unlikely or find another way to say it- feels like it should not have to be stressed with the 'highly'.
BECAUSE of the simplicity of the statements, this is VERY strong. Nice one.
