O. Henry's delightful story of two loving, unselfish, "foolish" young people who sacrifice their most valuable possessions in order to buy something that the other will enjoy has delightful language that abounds in allusions, irony, and other literary devices. Among these are metaphor and simile. In the tenth paragraph, for instance, after Della pulls out the pins holding her hair and it falls to its full length, it is described as "rippling and shining like a cascade of brown waters," a phrase that is a simile. And, with humor, O. Henry points to his own metaphor: "Oh, and the next two hours tripped by on rosy wings."
After Jim arrives home and opens the door only to see Della with her short hair, he stops as immovable as a setter [simile] at the scent of quail. For, he has noticed that her hair is short. He reaches in his pocket and lays the combs down. Stella hugs them and then says, "My hair grows so fast, Jim!"
And then Della leaped up like a little singed cat [simile] and cried, "Oh, oh!"
Then, when Jim receives his platimum watch fob, the "dull precious metal seemed to flash with a reflection of her bright and ardent spirit."[metaphor]
One example of personification occurs in this line:
When Della reached home her intoxication gave way to a little to prudence and reason.
