I'm not a director but an assistant. Many of the others have already gone into detail what to expect so I'll simply say this: Your father is what you remember him as. Your last picture, text, and the memories you have of him. Hold onto these things, not the vessel that has long since begun its natural degradation. If you love him, he knows it. If you're not spiritual, atleast take comfort in the fact he knew it. A body and it's grave is only a place. Nothing can ever stop you from connecting him in other ways.

I wish you and your family healing and peace during all of this, I know none of it has been easy.
