Titles in short stories sometimes use idioms as a means of providing a hidden message or foreshadowing what will take place (look back at the titles of the other short stories you have read).
Dramatic irony is an important stylistic device that is commonly found in plays, movies, theatres, and sometimes in poetry. Storytellers use this irony as a useful plot device for creating situations in which the audience knows more about the situations, the causes of conflicts, and their resolutions before the leading characters or actors. That is why readers observe that the speech of actors takes on unusual meanings.
For instance, the audience knows that a character is going to be murdered, or will make a decision to commit suicide; however, one particular character or others may not be aware of these facts. Hence, the words and actions of characters would suggest a different meaning to the audience from what they indicate to the characters and the story. Thus, it creates intense suspense and humor. This speech device also emphasizes, embellishes, and conveys emotions and moods more effectively.
