Describe the narrator in "First Confession."

As a narrator, Jackie is open and frank, sharing some of
his amusement about his childhood feelings, although he is an older person when he is
actually telling the story. He seems to be speaking rather than writing, and it is not
clear that he has any specific listener in mind beyond his anonymous audience. He is a
perceptive narrator, successfully transmitting his feelings of anger and indignation
against his sister, his being bemused by Mrs. Ryan, his apprehensiveness about the state
of his soul as he has learned to judge it in the punishment-driven household, and his
fondness for the understanding and friendly priest. Words like fastidious, mortified,
and indignant suggest his familiarity with a high level of diction. Jackie is also
inventive as a speaker, using combinations like heart-scalded and a religious woman like
that, you wouldn’t think she’d bother about a thing like a half-crown. There are a
number of Irish idioms and phrases, particularly in the dialogue, such as Was it the
priest gave them to you?, Begore, and Jay.
