It's nice that the family and cong are trying to somehow include the community in the service. With so much emotion in what seems to be a loving community, I think this 'open house' type of event will leave the mourners feeling empty. My guess is that the elders will try to create a warmer style of funeral talk, but having it in the Kingdom Hall, I don't see much real comfort for the community.
The difference between a JW funeral and a normal worldy funeral is worlds apart.
My guess is that the attendees will feel empty and confused.
-Aude.
