Has Etiquette Gone Out the Window?

[PamNY]

That does sound rude, but rudeness isn't new. There are just new ways of manifesting lack of social skills.

Was the hostess by chance new at entertaining? I cringe to think of the mistakes I probably made in my twenties and even thirties. Entertaining is a skill, like anything else, and takes practice.

If the hostess is someone you like and want to help out, you can, as a guest, help with chatting up people who seem left out, that kind of thing.
