“And he remembered the day when he and Eileen had stood looking into the hotel grounds watching the waiters running up a trail of bunting on the flagstaff and the fox terrier running to and fro on the sunny lawn, and how, all of a sudden, she had broken out into a peel of laughter and had run down the sloping curve of the path.”
James Joyce, A Portrait of the Artist as a Young Man (New York: Oxford University Press, 2008), pg. 58
Joyce uses delayed specification to reference in introducing this Eileen character going into great detail how he felt about her only to mention how the main character wanted to hold her but didn’t, and then never mentions her again. Then when he is back at school his rival teases him about a girl then Joyce doesn’t even bother to give “her” a name and continues to mention “her” in various other scenes.
