Millions of Readers, Eighteen Editions, One Trusted Resource From social networking to social graces, the name Emily Post has been the definitive source on etiquette for generations of Americans. That tradition continues with the 18th edition of Etiquette, which welcomes a new generation of Posts�Anna Post, Lizzie Post, and Daniel Post Senning�the great-great grandchildren of Emily Post. Led by Peggy Post, author of the 16th and 17th editions of Etiquette, this team shows how twenty-first-century manners are a combination of kindness, confidence, and awareness. New trends, topics, and societal hot zones include: When is it okay to �unfriend� someone on Facebook? If I�m in a middle seat on an airplane, do I automatically get both armrests? A business client is sick with a cold�am I obligated to shake his hand? Is it rude for guests to tweet from a wedding? Do I have to buy a gift if I attend a destination wedding? Can I email a condolence note? Should I cover up my tattoo for a job interview? The Posts don�t stint on classic conundrums, either. Emily Post�s Etiquette includes advice on names and titles, dress codes, invitations, table manners, workplace frustrations, and weddings. According to the Posts, though times have changed, the principles of good manners remain constant. Above all, manners are a sensitive awareness of the feelings of others. Being considerate, respectful, and honest is more important than knowing which fork to use. Whether it�s a handshake or a fist bump, it�s the underlying sincerity and good intentions of the action that matter most.
