Seeing the body of the deceased facilitates grieving, probably by establishing the irrevocable fact of death. Permitting survivors to express their feelings and reminders that grief is a normal process are helpful. Gentle review of the lost person's last days of life, last conversations, and last exchange of words and talking about the deceased's general life-style help initiate grieving. Most difficult to remember and most obstructive of grieving are hostile interactions with the deceased and any other interactions that leave the survivor feeling guilty. The more negative these interactions were, the longer it takes to begin recalling and discussing them.
Presence means more than words.
Someone who can remain calm and accepting in the presence of a weeping, angry, or bitter mourner is highly valued. A hand on the shoulder can be just what is needed. Helping the griever complete memories of the deceased also facilitates mourning. Old photograph albums and letters can be helpful in this regard. Patience over the long haul is essential because many acquaintances disappear from the scene within two weeks of the loss.
