I'm Crying Over 'No Graveyards'

I am planning to build a graveyard - just as a place to keep all the gravestones and urns so the ghosts don't break every single appliance at home. But I'm personally kind of glad that the death process & ghosts are the way that they are now just because the way it is in real life it freaks me out, especially after loosing people and pets that I loved.

And since as far as I know, the haunted house is a type of residential lot, I will have some sim(s) living there, pretend they are some sort of gravedigger. I haven't fully understood how the game handles gravestones, but I will make sure to play them often and have them interact with the urns and gravestones so the ghosts don't vanish. I'm so attached to my sims I would be sad it the game just deletes their ghost.
