A solo visit from Lizzie Post this week to discuss cross-cultural kissing, cross-office whistling, and the essential origins of all etiquette rules.

This month The Posts advise on times when haircuts are more important than family, making offers you don't actually intend to follow-through on, and using children as scapegoats - but it's all in the name of politeness. Really.

We are delighted to invite our friends the Posts back to our table to answer your etiquette dilemmas (and the timing of this invitation has nothing to do with guilt about a gift from us that might have been lost in the mail).

We talk to Judith Martin, aka Miss Manners herself, about the lost art of discretion and her own etiquette lapses (or lack thereof).

On his own “The Dick Cavett Show,” talk show icon Dick Cavett traded stories and witticisms with everyone from Grouch Marx to John Lennon. He’s now a featured columnist for The New York Times. Dick talks about being a little kid with an over-sized voice, and then he puts those pipes to use with killer impersonations of Hepburn and Hitchcock. There’s etiquette advice somewhere in there, too.
