characterization in the snow

In Hunters in the Snow by Tobias Wolf, characterization of the three characters is very prominent.  Throughout the story, their actions and conversations reveal their personalities.  This begins at the commencement of the story. Kenny's first line is "He looks just like a beach ball with a hat on, doesn't he?  Doesn't he, Frank? (par. 4)"   This introduces Kenny and Frank's endless criticism of Tub.  The food falling out of his coat when he runs from the truck also hint at his problems with over-eating, even when he later lies about being on a diet.  Tub's actions; complaining about his friends' criticisms, lying about his problems, and and shooting Kenny; show his insecurities.  Similarly, Frank talks about his marriage problems and his new love, revealing his unhappiness.  Kenny's constant jokes and insults characterize his attitude while also leading to his (supposed) death.  All three characters are characterized by their slang and unsophisticated speech.  Ultimately, their problems and personalities are revealed, but it is ironic that the one with the real problem, Kenny, is not helped at all in the end.
