HypersomniacLive: The reason we cry and grieve is not because the diseased wants us to, and I don't think that we do it over their demise or with their fate in mind. IMHO, It's a way of expressing our pain and inability (often even unwillingness) to deal with the fact that a certain beloved person will no longer be part of our daily lives in a physical way, we grieve because we won't be able to interact and share moments of our lives with that person ever again, we shed tears because their demise leaves a big empty spot in our lives that we can't fill. Sometimes, there's even some guilt in the mix and the knowledge that one won't ever have a chance to do right by that person can be pretty heavy.
Essentially, we grieve over ourselves, over the state their demise leaves us, not them; yes, it is rather selfish, but it's a reaction born on a subconscious level and one probably doesn't even realise it unless they give it some serious thought, still it's part of human nature and I don't condemn it.
Exactly so. And I do not begrudge anyone the period of mourning that follows a death. I go through that myself. It is natural, healthy, and as you say, has as much to do with our own feelings of loss as it does with empathy for those gone.
I can understand this grief being resurgent at a funeral as well, since seeing others triggers more memories of the deceased and makes the loss even keener.
My stance on the celebratory wake is that it should come once the primary grieving is done, much of which has already happened in private before the gathering. A wake enables people to find strength in each other and begin the process of resuming living. It also celebrates those who have passed, and helps us keep them alive in our memories, by giving us a final experience of them that is not centered on death, but on the connections and impacts they made on everyone around us in life.
