In “The Necklace,” we see several instances of personification. Let's look at a few of them.
In the very first paragraph, we are told that perhaps fate made an error with regard to the protagonist, Mathilde Loisel, for she has been born “into a family of clerks” with little wealth. Fate is certainly an impersonal force, yet here it is personified as having the ability to make a mistake.
Further, we are told that “the dirty walls, the worn-out chairs and the ugly curtains” of the Loisel home torment Mathilde. These inanimate objects cannot, of course, really torment anyone. Here they are personified, but it is really Mathilde's own resentment and dissatisfaction that torment her.
Later in the story, we read about the tattered “old night cabs” that seem to be “ashamed to show their shabbiness during the day.” These cabs aren't really ashamed, but the personification here is quite delightful, for we can picture the cabs slinking around with their “heads” lowered, trying to hide until it gets dark.
