I love the way you use rhyme in this, internal as well as external. It works so well because we have the story in the notes to guide us. I wonder if that story, the first part, meeting the psycho, could somehow be incorporated into the poem so that the note would not have to carry the development of the story. It should not need to lengthen the whole thing by more than two lines at the most.
I know I am renowned here for writing copious notes but the explain things in my poetry rather than telling the actual tale. That is the job of the poem.
Not only is this a Halloween poem, it's a true story. I hope they caught the guy who assaulted you. Thank God you were all right. This story brings a new meaning to trick or treating at your house. This is very well written. Good luck in the contest. Have a great day and God bless.
