I have a recurring motif in my story. It's an object that appears multiple times. The object itself has traditionally had a meaning given to it which is the same as one of my main themes of my story. I thought it would be interesting to place this motif in the story to help emphasize the theme. However, I've been questioned as to what that object means by people who have read the story. Should motifs need an explanation from the author or should they be left up to the reader to interpret? I really, really hate force-feeding my reader with what everything means. I love stories that make people think and come up with their own conclusions about things.
