The only thing that my family could do that would piss me off is if they spent a lot of money on a casket. That is the dumbest thing I have ever heard of. I wouldn't want them to spend a lot on a monument either but at least I understand that. Dropping 10 grand (or even 2 grand) so that somebody can rot in a fancy box is just retarded.
It gives me an idea for a business though, casket rentals. For $250 you get to lie in the $10,000 Cadillac casket during your funeral, even be lowered into the grave if you want, but as soon as the funeral procession leaves, we're going to pull you out of the hole, throw your ass in a $50 body bag or maybe a cardboard box, put you back down, cover you up, and the casket gets a quick shot of lysol and goes back to the funeral home for another carcass. Burying that thing is just too much of a waste.
