That is so true! I have had relatives who on their "death bed" told us who could ride in the FIRST CAR etc (ha) It went along with how funny they were in life, at literally their last minutes, having it their way!
We had an aunt who after her two sisters died, had a few of us cousins go BUY her a GRAVE in a certain cemetary, she wanted a "view, a nice TREE nearby..and maybe a stream" No kidding...and guess what! We found one,she was happy (she wasn't dying but had been ill) She died about a year later and at the prayers at the grave we looked around and saw she got what she wanted.
The strangest experience is shopping to buy someone something to be Buried in. WE had to do that too, for a diff aunt...and without meaning to we would horrify the salesclerk, since of course no one was "trying it on" and it's purpose etc.
Another point about this is what people want to be buried with....personally I'd rather leave my jewelry and my Bible to my granddaughter but I have seen some people buried with them. You never know what a person wants to do, until you ask.
Oh, my God, I just ate my brother!
