My grandfather still gets snail mail like that and he's been dead 22 and a half years.
This one obnoxious jerk called here one day demanding to speak with my dad. I told him to write this down and then I gave him directions to the cemetery.
Then I told him, "My father is buried there. Feel free to drive out there and talk to him all you want. I can't guarantee that he'll answer you though. But, by all means you're welcome to give it a try".
Then I hung up on the jerk. He never called back. lol
