rodewet,
I cannot begin to imagine what losing a 3 1/2 year old son is like. The last picture of your family by the casket is just too much to take. Bless you, my friend and may your son find grace and love in God's presence.
earllogjam,
I agree that funerals seem like a very bizarre practice. Especially open casket funerals. However, as I get older and as I attend more funerals of people who were close to me, I have come to find two things about funerals to be important (to the living, that is).
1) Funerals, especially open casket ones, seem to provide a necessary visceral and emotional function in the grieving process. Truly seeing the person who has died and even touching them seems to be very important in helping people move on from the sense of unreality about the person's death, to beginning to accept it. This was so strikingly true for me at my father's funeral and my mother's funeral. Even through the odd artifical cosmetic appearance that a made-up dead person usually has, my memory of my mother or my father in the casket seems to be indelible after all these years.
In another example, I remember something very odd when I was at the funeral of my 95 year old grandmother. When she died she was still living at her apartment and getting around with the help of a few younger relatives. However she was so fragile and she had all kinds of health problems. I was always worried about how she was going to get through the next day without something really bad happening to her. At the funeral I remember at one point looking over at her in the open casket and having this profound warm feeling come over me that now she was safe and far from any more suffering or harm. Strangely, the feeling mostly disappear when I looked away and it would come right back as I looked at her. Although I am a religious person, I am not implying anything supernatural here. I am only saying that the psychological benefit of actually viewing her in the casket was for me very important and profound. I can recall some of that feeling now these 20 years later.
2) Family and friends show up, view the deceased, and make an "event" out of the passing. This is very important. When I was younger I couldn't figure out why all the family members would come to a wake or a funeral and end up discussing every day life. I expected people to not be able to think or talk about anything else but the deceased person. Later on I realized that the "showing up" is the most important thing. A person's life is honored by the fact that family and friends have suspended every day life and have come together for this sole purpose.
Later on, being in the "receiving line" at funerals for my father and mother, I realized how extremely important to me it was that all kinds of people showed up at the wake or the funeral. Especially people you haven't seen in years and people only peripherably related or acquainted with the deceased. This is an important aspect of wakes and funerals. In the midst of your grief, it is extremely soothing to see your family members and close friends, but just as soothing to see the basketball coach or someone you would never have expected to show up, coming down the receiving line. It helps to constantly remind you that the deceased was a real person who affected the lives of many people. It helps you hold on to the fact that the life of the deceased was valuable and from that so is yours.
So earl, here is the advice that I give to anyone who asks me for it. If you know someone pretty well, who has had a close family member die whom you did not know, it is always useful for your friend for you to go to the funeral or wake. Your presence there is always treasured at the moment and long afterwards. You don't even have to say anything to your friend and the other family members. Just going through the line, locking eyes for a moment and shaking some hands is extremely helpful.
As for the open casket. If you don't actually know the deceased, its perfectly ok to just turn from the end of the line, stop for a moment and look at the deceased for a couple of heartbeats and move on.
There you go. My two cents on your funeral question.
