A Perfect Day for Bananafish

This story was odd to me. I am not sure I get what the main point is in this story or what the author might be trying to get across. I feel like, if it was not for the begining conversation between the wife of the Seymour and her mother; the way Seymour was acting was not all that pecular till he gets on the elevator then he gets all weird. Besides acting a little goofy sometimes I would have never expected him to shoot himself. I guess it the begining conversation really foreshadowed what was going to happen because the mother was being so over bearing about her daughter being careful.
