The End of the Party

• Guests at a dinner party are expected to stay for each course of the dinner. It is considered rude to leave before coffee, which typically follows the dessert course. After-dinner talk usually lasts anywhere from 20 minutes to an hour and a half after dinner. The host will always cue the end of the party by clearing the table and beginning to wash dishes, or inquiring politely about each guest's transportation home.
  
  

Leaving Early

• If you must leave a dinner party early, inform your host privately and as early as possible, preferably the day before the dinner. Always give an acceptable excuse, such as a sick child or a long drive home, and apologize sincerely. When you leave, do so as quietly and discreetly as possible without making an announcement, saying polite goodbyes to close friends only. A good host will understand your reasons for leaving. Never leave a dinner party early because you are bored.
  
  

Overstaying Your Welcome

• Overstaying your welcome at a dinner party is considered extremely rude. Never suggest the host open another bottle of wine, as he may feel pressured to comply with your request. Always respect the wishes of the host, even if another guest is attempting to stay late and make idle conversation. If the host begins to wash dishes, discuss how late it is or inquire about your transportation, consider this a polite cue to leave the party.
  
  

Appropriate Goodbyes

• When leaving on cue with the party's other guests, say polite goodbyes to any close friends at the dinner party, and tell new acquaintances that it was lovely to meet them. Thank the host last, and compliment the dinner appropriately. If you are on close, friendly terms with the host, follow the dinner party the next day with a call to thank her again.
