getting a "do-over"

I attended a memorial service today for a doctor husband of a Korean friend of mine.  I didn't know until today that it is traditional, in the Korean culture, to bury a family member who dies within three days of the death but then to have another memorial service on the first anniversary of the person's death. The anniversary service today was a beautiful event with heartfelt comments, excellent music and a lovely catered luncheon.  It occurred to me that having this first anniversary tradition gives family and friends a chance for a do-over.  I'm guessing it's true for many people, I know it was for me, to look back after a funeral and think "Oh, I should have done... or someone should have said... or why didn't I remember to..."  I don't expect the tradition to catch on here but it's not a bad idea.
