Dear Avigal,
We offended the husband of my wife's best friend by not allowing him to participate via Zoom in our Passover Seder last year. When I saw him recently I sympathized with his desire to be with his family who were visiting us and I assured him that it was nothing personal - others had asked for this in the past, and we said the same.
He is brogas. Never wants to speak to us again. Says we don't understand that family togetherness is the whole megila, the highest value, etc.
I apologized again for the hurt that this exclusion caused him, but said that this is our policy and it was nothing personal.
I can't apologize for what we did, because we'd do it again. I can only apologize for the fact that what we did caused him such pain and invite him to be with us in person in the future.
Now he's in town and pointedly not visiting us. On one hand, fine! Grow up!
But do I have an obligation to continue to apologize? And for what?
