So what should I have carved in my headstone or marker?
I was thinking about, "Here I sit broken hearted, tried to die but only ...".

I've had a few things I've thought of over the years ...

1) Fuck Everybody!
2) Piss On The This, But Don't Step On It!
3) Please, Look Up The Word "Neidbau"!

LOL I had to look up "Neidbau" but don't really see how this applies.

I'm not one for cemeteries (other than maybe to ghost hunt at night; I guess) ...
I look around and think that if we just incinerated people and MAYBE just buried
their urns, that we could still have memorials and cut down cemetery space into fractions ...
Hell, in Europe (some parts) they dig you up and replace you after 40 (or so years) ...
[Catacombs were the dumping grounds for that initially] ...

So, you get how "Neidbau" is ironic to my belief(s) now?

Kinda like this:

That's pretty funny but who could hate a park?

That's just an example ...
I still think you missed my point ...
