The sentences that are examples of irony in the story are:
Irony:
- "Thanks for picking today, of all days, to get stuck for twenty-six minutes." (This expresses frustration that the subway chose that particular day to malfunction when Janelle was counting on timeliness.)
- “I would never make such a silly mistake.” (This is ironic because Janelle did, in fact, make a silly mistake by thinking the supervisor was starting that day.)
Not irony:
- Janelle ran the half-block from the subway station to the office.
- “Has the new supervisor come around yet?”
These two statements reflect straightforward actions and questions and do not convey irony.
