Broken Rules in The Road

Fragments, lots of them.  Occasional contractions without apostrophes.  Dialogue without quotation marks. Missing commas.  It's like Grammar Rules Gone Wild.  Perhaps it's because I spend several hours a week reading and grading papers that these things stand out as badly as I do when standing in a group of Yup'ik women (my height, that is).  

Surely I'm not the only one to have noticed this, right?  So what's the point?  Are any of you finding that it affects the story?  Why do some contractions have apostrophes and others don't?  I'm having a hard time getting into the story because I can't get past all the broken rules.  


Any thoughts?
