You don't have to "bemoan" their deaths, just a place to have a quiet time to spend with them. But , again, it is different for a parent than for a friend. For the friend do go to a bar and have a beer, but for the parent something a little more respectfull maybe.
Of course you are free to your opinion, but I disagree.
I have never visited the gravesites of any of my grandparents or anone else I was close to.
I spend time with them all the time.
I don't understand how spending time with a headstone 6 feet above a corpse in a box equates to spending time with them, any more than sitting on my grandmother's porch thinking about when we used to sit there and talk.
I spend time with loved ones who died every time I think about them.
I don't need a cemetery for that.
(and I know some very quiet parks, by the way)
