I'm not sure what your question is. When my father passed away it was an end to his suffering. I've often wondered what the funeral director thought, as we were laughing and joking around like nothing was wrong. Yet the Alzheimers had taken him from us long ago. Yet there are things of his which bring back good memories; and while I felt a bit ghoulish, not long after his death I told her that if there was only one thing of his I could have it would be his TO35... knowing that if I didn't speak up it would go to a friend of his who had already mentioned it.
I go to the cemetery occasionally to help keep the gravesite up where he, my brother, and several other members of my family are buried simply because she likes it kept nice. His Ferguson I will use, if I ever get a place to store it here; and a few other things of his which I can use. Aside from that, what's wrong with keeping things if they bring back good memories?
