John Fleck pointed out that I shouldn’t argue when people use the word “ironic” to mean “sarcastic or campy,” since language changes over time, and the word is evolving to mean what people use it to mean.

His response was, pedantically, “No: I am surprised, you are merely astonished.” Nowadays, astonished and surprised mean the same thing, but at the time, surprise was strictly about catching someone unawares, whereas astonishment indicated … anyway.
