I agree with this wholeheartedly. And let's not forget that there's really only a certain amount you can do with 75 words, so in my opinion a little ambiguity is not only unavoidable, it's probably useful in getting more out of the story through varying reader interpretations.I believe that all art - including writing - no longer belongs to the creator (artist, author, etc.) once he/she puts it out to the public. It belongs to those who behold (read) it. All of us interpret art differently. And that's how it should be.
Which means that you don't need to feel dumb if you've chosen to interpret it in your own way. Think of it as extending the usefulness of the storyI have entirely missed the point of some stories I've reviewed, and always feel dumb when that happens.
