tried to focus on a particular aspect of this historical moment: the failure of mourning. This is something I haven't seen a great deal of in the writing around this disaster. And my view is that you write about disaster by writing around it, by writing allusively.

I became aware of just how fleeting the sense of happiness was, and how flimsy its basis: a warm restaurant after having come in from the rain, the smell of food and wine, interesting conversation, daylight falling weakly on the polished cherrywood of the tables. It took so little to move the mood from one level to another, as one might push pieces on a chessboard. Even to be aware of this, in the midst of a happy moment, was to push one of those pieces, and to become slightly less happy.

Joyce's writing in Dubliners contains some of the most unshowily beautiful sentences in the English language. I learned from him that if you write a good, clean line of English, you can get under a reader's skin. The reader won't even know why, but there you are.
