The central idea of Elizabeth Tallent's "No One's a Mystery" revolves around the tension between innocence and experience.  The unnamed narrator creates a picture-perfect life with Jack and imagines them having children and living together forever.  She maintains this dream even as Jack pushes her to the floor of his car because he sees his wife driving past in the other lane.  Jack, on the other hand, knows that this relationship is simply a fling and that one day, the narrator will realize that he is not the man for her.  Jack is too burdened with the hardships and monotonies of life to see any way that his life could be different, yet the narrator is too innocent to consider that her romantic dreams may not come true.

When writing about the central idea, you are addressing the theme of the literary work--state the theme in your thesis statement and use points of argument and textual references to develop your writing.
