The details you share about someone should not outrun their chance to speak for themselves.

Speaking about an absent person shapes how a room will meet them, and once a detail is out it cannot be given context by the only person who has it. Illness, money trouble, a separation, a diagnosis: these are theirs to introduce. Sharing them early is often meant warmly and still removes a choice that belonged to someone else.

Before you mention something personal about another person, ask whether they have told this group already. If not, leave it. If it needs saying for practical reasons, ask them first.
