Sorry for taking forever to respond. I decided to get sick for like a week for a lark. Wasn't all that fun though. 1/10 would not recommend.
On a more serious note, yeah. I figured it was probably that I just took things too literally. Though it also depends on what things are a metaphor too. Since I tend ot be really interested in metaphors for mental stuff going on with the character. Which is why I like Silent Hill so much. Since the entire city tailors itself to each person who enters and creates one giant metaphor from the person's psyche. (Which is also why I'm so mad that the series went so downhill after 4 and we'll never get Silent Hills)
Both that, and the fact that I am not really all that great at actually putting ideas into practice is in part due to the fact I've never really had any real classes for this kind of thing. I've kinda just been winging all my writing ability since day one.
