What happens after I died?
Having no own family by then, and expecting my parents to be dead by then, foreign people I never knew will come and do with the dead corpus and my former belongings what they want, following my last will as they pleases, so its absolutely possible they will ignore it as well, and I will not exist to care for that anymore.
That is what will happen.
I like this author who has just two words on his gravestone in some natural reserve in the US: "
No comment."
"No drama" also would have been good.
All this rite and ritual is not for the dead, but for the survivors. Do not sent the deceased those expensive flowers. Do that while they still are alive. If you missed that, save your money later on.
