Trendspotting Oh, Behave! From grandes dames of good behavior and modern advocates of fabulousness, manners make a comeback. "Emily Post is the literary It Girl of the moment, and she has Joan Didion to thank for it. Despite the fact that she's been dead for nearly fifty years, Post and her seminal guide to good manners, Etiquette, have come up in nearly every review of Didion's best-selling new memoir, The Year of Magical Thinking. Critics can't resist mentioning that in the dark days after her husband's death in late 2003, Didion found great solace in the "Funerals" chapter of Etiquette's first edition, published in 1922. Psychologists, poets, and philosophers could theorize all they wanted about the stages of grief and how to cope, but in Post, Didion found the reasoned voice that really offered relief. It was the relief of ritual -- of an established code of conduct that could safely transport her from one difficult moment to the next, without the burden of hand-wringing analysis."
