words on pages

I hear people say the author could not have put that much into what they were writing. My English teacher is going beyond what the author ment. I can understand their feelings because it does seem hard to believe that everything in a book, that makes sense when you think of it as only a story. When you turn the story into the author pouring out their hearts onto pages expressing everything that makes them a person. That's when it becomes easy to see a meaning beneath the words. "This is for you... everytime I write everytine I open my eyes I am cutting out a part of myself to give to you" (anis mojgani). So why do people struggle with the idea that when a writer talks about a character having a problem he couldn't have been talking about a greater problem that he sees in the world.

this is my 2 cents
