"The wind was cold and harsh, and it whipped at their faces."
This sentence personifies the wind by giving it human-like qualities of being "cold" and "harsh". It also describes the wind as actively "whipping" at the characters' faces, further suggesting a purposeful action typically associated with a living being.
This use of personification helps to enhance the setting and create a sense of atmosphere. It also underscores the harshness of the environment that the characters face, both literally and figuratively.
Keep in mind that *The Outsiders* is a realistic and straightforward novel. It focuses more on character development and social commentary than using complex literary devices. However, the example above shows how personification can subtly contribute to the novel's overall impact.
