I actually kinda get this story. lots of things make us lash out at our partner or have stupid non-sensical arguments that weeks or even months later, no one remembers what it was about. in this case, it wasn't about donuts. i think it was about not being paid attention to (http://dynasty-scans.com/chapters/bittersweet_donuts#4). as to the make-up at the end, the blonde character (while hurt), made an effort to "fix" the situation. that was sweet.
everyone may disagree with me, but (to me) the story is clumsy and resolves itself straight out of left field (i.e. illogically). however, it does highlight how stupid little arguments get blown out of porpotion.
