That is the best part and I'm glad you pointed it out. If it happened, (big if) fucking huzzah for someone saying what needed to be said. And if she wrote it, which I would guess she did, since it looks like it was written on the inside of a box of milk duds, then she loathes herself so much that she knows that this is something that a random stranger would conceivably say to her. Even in the depths of her delusion, she subconsciously knows that she is a disgusting pile of lard.
