That is interesting. I have been to many LDS funeral services, and they are full day affairs, even 2 days.
Viewing, the night before, then the next day, another viewing, time to gather with the family, a full church service, memorial, trip to the cemetery, short service, back to church for Relief Society luncheon, or at home, depending. (Side note, best food, ever...usually ham, "funeral potatoes, rolls, jello salad, cakes).
Generally, LDS funerals are lengthy and filled with family members, church members, neighbors.
Interesting, that Tammy's funeral was brief.
