Berlin reuses some names across stories, while other stories use different names for the same woman. For example, in "La Barca del la Ilusion" the heroine is named Maya while in "The Wives" her name is Laura, although it seems the same woman is featured in both; and the children in both "My Life is an Open Book" and "Noel, 1974" are named Keith, Ben, Nathan and Joel, yet their mother is Claire in the former story and Maggie in the latter. Why do you think the author used this technique?
