My mom got a bill from a Dr. for my dad. Dad had been dead for three years and the date of the visit was current. Mom, being mom, called the Dr's office and said she was really up set because her husband died three years ago and he came back to see the Dr. and did not stop in to see her.
The girl in the office asked mom if she would give her dads forwarding information so she gave the girl the address of the cemetery with the lot #.
P.S. the Dr was a pediatrician
