Addressee unknown!

That is what I am writing a lot of on mail that is being delivered to my house. For not 2 previous owners but 3! And its not just junk mail. In the past two weeks I have received one person's Social Security Statement, and a hand-written note to another....

I guess this is what happens in a 68 year old house... but man it is annoying, especially since I do not have my own mailbox that I can just dump them back into! ( I have a mail slot in my front door ... so cute!)
