Here’s the classification of the sentences based on irony:
Irony
- Thanks for picking today of all days to get stuck for twenty-six minutes
- I would never make such a silly mistake
Not Irony
- Janelle ran the half-block from the subway station to the office
- Has the new supervisor come around yet
The first sentence is ironic because Janelle is sarcastically thanking the subway for delaying her on an important day. The last sentence is ironic because it reflects Janelle's acknowledgment of her mistake in a way that contradicts her claim of never making a silly mistake. The other sentences do not contain irony as they are straightforward statements.
