Sometimes, slight sense of irony in a sentence can add color to what would be a pedestrian line of writing and irony can brighten an otherwise flawed expression. It’s simply about the “art of writing” when one observes art in a piece that seems flawed.
Art of writing may be fused throughout the whole, ordinary, unexceptional flawed piece, to give it an air of mystery and aloofness. It is flawed prose in one sense, but how the piece is structured or designed gives an illusion of art through each line. How one does this is tweaking; in sum, making it sound interesting.
