Sometimes I find that the narrator for stories is just far too boring in most stories that I read. I like narrators that either have more fucking personality or just say the most random shit (for example the wonderful Lemony Snicket in Series of Unfortunate Events). Give the narrator some fucking sass. Make them swear. Make them question what the fuck they're witnessing.
Make your narrator a character. Make them make the reader question the character and story by throwing in off hand comments when telling the story. Make them insult the reader. Make them call us all the fuck out in the most insulting way possible.
