Etiquette experts are weighing in on various social issues, including what questions are still considered off-limits and how to navigate polite interactions. There appears to be a focus on refining social behaviors, such as tipping and dinner party etiquette, with some outlets offering guidance on how to cancel plans or behave in certain situations. The reports also touch on broader topics like reputation repair and health education, although the connections between these issues and etiquette are not entirely clear.
