In the story "Araby," why might Joyce not mention the object of the narrator's affections until well into the story?

In his story,
"," Joyce does not mention the
object of the narrator's affection as Mangan's sister
until the reader is
well into it. One reason that he may have done this is to make sure the

reader is focused on the character of the narrator: how he thinks, how young and
idealistic he
is, how little he knows about the affairs of the heart. Another
reason could be that Joyce wants
to keep the woman anonymous to indicate that
the fact the narrator is "in love" is
more important than the object of his
affections. We see the young woman as an ideal, not a real
person but someone
the narrator has created to suit his own romantic purposes - all the better

to set him up for his inevitable disappointment. By the time the reader knows who the
narrator's
love object is, he/she relates to the main character and is on his
side, rooting for him, even
knowing that he is about to learn a hard lesson
about life and love.
