What is the author's style in The Advertisment by Natalia Ginzburg?

Throughout The Advertisement, Ginzburg makes use of recurring similes in order to describe and characterize the relationship between Teresa and Lorenzo. A simile is a figure of speech in which one thing is described as being like something else in order to illustrate a particular quality or set of qualities.

Teresa and Lorenzo both describe their marriage in disparaging terms, using several recurring similes to portray the negative qualities of their relationship. At one point, their marriage is described as a monster. Teresa says that they would sometimes quarrel over a single word she might have used unthinkingly, upon which, she says, "he'd drag out all the possible hidden meanings, so that word would grow and grow till it was like a monster." Likewise the negative elements of their marriage grow and grow to the point that the relationship becomes like a monster—an evil, violent, destructive thing that is out of their control.
