Etiquette Experts on Dinner Party Faux Pas for Southern Living

For Southern Living, I’m working on a story about rude dinner party behaviors. Looking for comments from etiquette experts: - What’s the most common faux pas guests make at dinner parties? - How do etiquette rules evolve with the times — for example, are things like arriving fashionably late or taking photos at the table still considered rude? - What should a good guest always do before leaving a dinner party — and what’s something most people forget to do that makes a lasting impression? - Should you always bring a gift for the host? - Is there a polite way to handle it if someone brings up politics, diets, or other controversial topics at the table? - And for hosts, what are the rudest behaviors they should avoid themselves — things guests might silently judge?
