We were very fortunate with the people at the mortuary who helped us. They were very tender and kind.
My H decided that he wanted to be present when Jim was cremated, which I hadn't thought of, but it turned out to be a very symbolic last thing we were able to do for him. Very hard. That's when DS23 chose to say his good-byes as well.
Walking through this stuff is the most terrible thing I can imagine facing.
