"A & P." -- What does the narrator reveal about himself indirectly? What sort of transformation does the narrator experience during the story?

The narrator, obviously an adolescent boy, is a cashier at a local grocery store. With the use of the descriptive vocabulary the narrator is able to reveal something significant about his character. He is extremely observant towards other people’s appearance and is able to match their physical appearance to their individual behavior. For instance, when he says; “Walking into the A & P with your straps down, I suppose it's the only kind of face you can have,” which was implying that she felt as though she was attractive and wanted everyone to look at her. Also, he calls her “queen” or “queenie”. He may mean this in two different ways; either the way she holds her head up high and leads the other girls around the store signifies her absolutism, or he sees her as a “queen” or perfect in his own eyes. The descriptive wording shows that he over analyses everything and everyone he sees. The transformation that the narrator experiences is quite obvious. He starts off as a quiet, reserved young boy that goes to work to merely to put in hours to get a pay check at the end of the week. As the story progresses he not only manages to face this girl he so madly adores, but stands up for her and himself by quitting his job.
