The aunt tells a story with a moral, but the children ignore the lesson.
Explanation:
Situational irony is a literary technique that is used when an unexpected outcome occurs in a particular case/event. This means that a normal reaction to an action does not happen, rather the opposite result occurs. This is exemplified in the story above. After the aunt tells a story with rich moral lessons, it was expected that the children would pick the main points. However, this did not happen as the children were disappointed in the story and did not grab any lessons.
The right of people to express their opinions publicly without governmental interference, subject to the laws against libel, incitement to violence or rebellion, etc is known as freedom of speech.
