As much as I enjoy Didion, I still haven't read The Year of Magical Thinking. But I read her interviews and watched her do the talk show rounds when both the book and the play debuted. I fully understood the term and am now employing a great deal of it myself.
As in "surely if the biopsy was cancerous- especially a high grade-they would have gotten me the results by now."
I think it but don't believe it and work my way through another weekend of limbo.
