We have been planning the garden party for two months, 30+ people invited for this Saturday. Now with the news on TV about Queen's health we are unsure whether we should cancel it, and what to do if the sad news happens tomorrow or Saturday.
Would you find it appropriate to come to the big party in case of the Queen dies on the day?
YANBU - proceed with the event as planned.
AIBU - cancel the party, it will be inappropriate and awkward
