Sorry for the length of this, but I was recently reading an interview with Haruki Murakami, an absolutely remarkable Japanese author, and his response to one of the questions reminded me of you.  "Interviewer: It seems to be difficult for you to talk too much about the underlying meanings of your work.  Murakami: People are always asking me about the books: "What do you mean by this; what do you mean by that?" But I cannot explain anything at all. I talk about myself, and I talk about the world, metaphorically, and you cannot explain or analyze metaphors - you just have to accept the form. A book is a metaphor."  Do you relate to his answer? When people ask about the 'meaning' of your songs, is your thought process about the question similar to his?
the way i feel when someone asks me this is sort of like how i would feel if i were a chef, and then the customers eat the food and then ask me how it tasted
