In response to R. Wayne Snider's letter about the March 2 Doonesbury comic strip, I would like to offer Mr. Snider the definition of the word irony that can be found at Dictionary.com:
irony
1. the use of words to convey a meaning that is the opposite of its literal meaning: the irony of her reply, "How nice!" when I said I had to work all weekend.
2. Literature.
A. a technique of indicating, as through character or plot development, an intention or attitude opposite to that which is actually or ostensibly stated.
