Throughout the story, the author uses metaphor, irony and symbolism. The sarcastic irony comes from when he mentions that some women would be offended by his story, which many would be. The whole story is about mocking and being sexist to the female race. The author continuously mentions insecurities and flaws that some women have, which can be seen as offensive and inappropriate to some women.
The author treats the story like a joke, but there are probably very few women who enjoyed reading his work at all. He speaks jokingly throughout most of it, mentioning at the beginning how he had been drinking and now just wants to avoid his wife, which is the reason he writes a story. He procrastinates at first, not exactly sure what he will be writing about. He then becomes quite self-righteous and conceded, thinking he is the best writer and can make any girl beautiful. Again, the sexism and offensive is especially sensed when he says this, because he thinks he can fulfill every girls dream of being beautiful.
