WWYD?
Been living in our current properly for almost three and a half years. When we first moved in, and for up to around 6-8 months after, any mail that was posted through our door addressed to previous tenants we did the whole 'return to sender, not at this address' malarkey. We eventually stopped doing that though, as despite constantly doing it and keeping on top of it, it wasn't putting a dent in the flow of mail we were receiving for other people, so instead, we'd keep them for a few weeks (unopened), if no one arrived to collect them or chase them up, we'd bin them.
In the time we've been here, for one previous tenant in particular, I would honestly go as far to say that the amount of post we've received for him could fill up a bin bag, and then some. We've had some 'important' looking post as well as typical junk, but he's not bothered to come and collect any of it or ask if anything has been delivered for him, and frankly, I'm not going to keep walking all the way to the post box with his post every few days.
However, as it's now approaching Christmas, we're starting to receive what appear to be Christmas cards for the various different people/families that have lived here before us. None of the cards have return addresses, what do I do with them? It feels as though one has a gift card of some description inside, but with no return address, if I was to put it back in the letter box, how would it 1) get back to who originally posted it? And 2) find who it should have actually gone to?
Should I-
Post it back and hope some magical elves can figure out where a Christmas card came from?
Throw it away?
Keep hold of it in case the bloke turns up for it? (Unlikely, as he never has, not even for the important looking bits)
