Again, your and my perceptions are so far apart. My Son loved carpentry work and during high school attended a Vocational class where they built complete houses. His tool belt stocked with tools of the trade including his Estwing rough-in hammer burned in my shop. Irreplaceable. Priceless. He was 2 weeks from his 19th birthday when he died.
Sorry for your loss of your son. I do however think that it's different between when you lay your offspring to rest (to which I wouldn't wish upon anyone) vs laying your parents to rest.
In the end, objects only represent what the decased owners of those objects have meant to the living person who the deceased has had a relationship with. It's not the object who had the relationship, but the person who owned that object. In the end, for myself, it isn't the objects that determine the value to the living which the deceased once owned, but the impact the decased has had on the living person.
Perhaps my objectivity would change if one of my own sons died before myself, but again, wouldn't wish that upon.
Death waits for no one. Sooner or later, we will ALL face that journey.
When my mother passed away in 2003 and I was a only child living 800 miles away from my father, we had a heart to heart conversation on EVERYTHING he wanted done with his material possessions and who would get what if he were to die (in a will as well), which I alone would determine after his death as he left everything to me. That said, I would NEVER EVER not follow my fathers wishes. In that aspect I was very lucky not having to deal with siblings. that said, I speak from experience (from a very large family on both sides of my parents and wifes family) in saying that all siblings from the same set of parents don't hold the same common sense or values from "good" parents.
We are born with nothing coming into this world, and we will all leave the exact same way. Money however tends to screw the living up, not the dead.
I was the executor of my Aunt's "estate" when she died. She had no money, lived in an apartment, and left no will. After dealing with all the family on the stuff various people wanted, I wouldn't wish the scenario on anyone.
