The sentences that are examples of irony are:
- "Thanks for picking today, of all days, to get stuck for twenty-six minutes."
- "I would never make such a silly mistake."
These sentences illustrate irony because Janelle's frustration with the subway and her assertion that she would never make a mistake contrasts with her actual situation of being late due to a misunderstanding about the supervisor's start date.
The sentences that are not examples of irony are:
- "Janelle ran the half-block from the subway station to the office."
- "Has the new supervisor come around yet?"
These statements are straightforward and do not convey a contradictory situation.
