I think you raise some great points and your personal experience is relevant to the issues. Given that narrative studies is not your field of expertise, then it's understandable that you won't use the terms and ideas in your discussion. I was probably reacting to the dismissive tone of the discussion. I'm aware that implementing ideas from one field (e.g., story telling) to another (e.g., marketing) has its limitations, but rather than dismiss the ideas as cheap tricks, I think it's more interesting to identify those limitations and discuss them within the appropriate framework of both fields. This is something that it's really beyond the scope what I actually wanted to do in this post, which was write a story about two sisters having a cat fight over vaccines. :)
