Return to Sender: The Skanky McWhoreface Edition

So it's been a busy day. I have a lot on my mind and much more to do. So many things are swimming in my head as I pulled up to my mailbox today and retrieved the stack of mail meant for me. 

I quickly scrolled through the junk for important stuff...and noticed an elaborately addressed envelope. Heavy card stock, calligraphy, the works. My eyes scanned for the return address only to realize the intended addressee: my ex's former mistress-turned-wife.

I received mail meant for The Other Woman. 

Of course I laughed, because this shit is funny. I know how it happened. Dumbass McCheaterson changed his wife's name (from mine to hers) on a particular account, but didn't bother to change the address to their new love nest. Hence, the piece of mail goes to her name at my address.

Since there's no Emily Post moment for this, what does one do in such a delicate situation? Return it to sender after correcting the addressee to Skanky McWhoreface? Deliver it personally to the happy couple's new love palace? Burn it in a voodoo ceremony?

Really, I want to know. Because it's just sitting in my car right now with all the other junk mail from today's haul.
