What is the author's style in Exchanging Glances by Christa Wolf?

The narrative technique that Wolf uses in "Exchanging Glances" is called meta-narration. Through this literary device, the narrator both tells the story and also comments on how she tells the story. Critic Margit Resch writes that Wolf is "unusually self-conscious, even for a writer," and this tendency toward self-reflection emerges in her fiction. Early in the story, she tells readers that the details about her grandmother's sweater and button-up boots are memories from "that April day I have chosen to recall here." But memory is imperfect, and the writer's task, Wolf suggests, is to subject the process of recollection to an ongoing critique.
