my father is religious, I’m not and I don’t care what happens to my body after I die. Burn me, use me to feed stray cats.
To me, wasting money to buy a plot of land so I may be buried with them when I die is a stupid idea.
It is, however, his money. Who am I to disagree with him?
Unless you have a serious reason, not to be buried there, Then let him buy a plot. It isn’t like it’s going to hurt you or offend you. You’re dead at that point so I’m not sure your body is really going to care where you’re laying at. If you don’t believe in an afterlife, you’re dead and you won’t even realize it. If you believe in an afterlife, you probably still won’t care. So let him have his way if he’s willing to pay for it.
