This week we take a look at what we believe is an essential book about being 'coupled', which relates directly to the idea of caffection. Grandson of Emily Post (yes, that Emily Post), Peter Post has compiled Essential Manners for Couples. This is sensible, comprehensive advice on everything 'From Snoring and Sex to Finances and Fighting...' as the jacket says. Useful advice inside covers a surprising range of common and not so common situations, like signals we send, interaction with other couples, our actions in public, work (which the author labels, trenchantly the 'other significant other'), such things as sex when the kids are in the house, and having houseguests. Underlying all the advice is the simple rule of good etiquette. In this book, that rule outlines how etiquette applies to happy couples, and can be a terrific guide to calmer, stronger marriage. Our only disappointment in the book was its minimal attention to financial patterns in a marriage, money being number 1 or 2 on the list of marital stressors, particularly now. Perhaps that's another book. But for great advice on etiquette in happy coupledom, Peter Post's Essential Manners for COUPLES, ©2005 is 'essential' reading.
