My parents never lived with us - but for some reason we get mail for both of them My dad passed in 2000 and my mom in 2009. I used to try and send it back but finally stopped wasting my time. What is bizarre - we never got any mail for my DH's parents and they have the same last name as us.
We have no idea who lived here before us, my DH & I have been in this house for 29 years and we still get a boating magazine for someone with a name we don't recognize. At first I contacted the magazine to tell them they had the wrong address - they obviously don't care because they keep coming.
