Summarize:

Holidays or important dates in the person's relationship with the person she lost can trigger feelings of loss. Encourage her to plan ahead to commemorate those days. This can help her create a feeling of continuity with the past or create the sense that you are moving on. While it is particularly useful to develop a ritual for special dates, there is no reason why the griever shouldn’t plan to celebrate or remember the deceased any other day. There is a plethora of rituals he can use to remember his loved lost one. Which one he picks depends on his relationship with the person and what it was that once brought them together. Some examples include:  Preparing a meal that the deceased enjoyed. Watch a movie that the person enjoyed. Go on a walk, possibly where the two of had been in the past, and remember times spent together. Buy flowers on important days. Travel somewhere the deceased wanted to go. Listen to music that reminds the grieving person of the deceased. Look through a photo album. Ask her to write fiction, personal essays, or poetry that expresses and identifies feelings and blockages. You can encourage artists to paint or draw. Starting a journal can be an important step for dealing with emotions.  Ask her to try writing about the life of the person she lost. Alternatively, have her write about how that person has influenced her. Remind her that the deceased lives on through her. Memory books can help in the grieving process. Compile mementos, photos or stories about the deceased person. This helps one come to terms with the magnitude of the loss and to focus on the realities of one’s new life without forgetting the lost loved one. Place an open chair opposite the grieving person and ask her to imagine the deceased person sitting in that chair. Give the bereaved person the opportunity to speak to the person in the chair and say all the things that she would like to have said to that person.  Playing out situations from the past or rehearsing difficult future situations may help bring closure. The use of objects and memorabilia, such as jewelry and other objects which the bereaved person is comfortable with, can be used to facilitate talking and bringing the mourning process to a close. Some people will want to clear their heads or process their loss before trying to commemorate their loved one. Many people have difficulty talking about what has happened. It is your job to give the grieving party ideas about how to move on. It is not your job to force them to do something they do not want to do.
Get her to plan ahead for important dates. Encourage him to commemorate with ritual. Encourage her to express his grief through art. Create a memory book. Use the open-chair technique. Don't push.
