DEAR MISS MANNERS: I had a dinner party for eight people. Six of them, including my spouse and me, later tested positive for COVID.
Prior to the party, we all tested negative, but obviously one or more of us was not symptomatic at the time. Five days after the party, the first person reported that he tested positive, and I contacted the rest of the guests and let them know. Over the next week, most have confirmed that they have the virus.
I feel certain that the party was the event that precipitated this, and feel terrible that my guests are ill because of it. What is the right thing to do now?
GENTLE READER: Oh, dear. Not your fault, of course, but it was your party.
You have already done the right thing in notifying people immediately, and, Miss Manners trusts, telling them how terrible you feel. This is a rare occasion where the non-apology so often used illegitimately by guilty people -- a variation of "I'm sorry you feel that way" -- is legitimate. You do feel bad that they feel sick.
There are two more things for you to do -- or, rather, one to do and one not to do:
You should check up on your guests occasionally to see how they are doing, and you should refrain from any speculation about who was the carrier. Everybody tested and everybody attended in good faith, so no good can come of targeting anyone.
