This isn't aibu but posting here for traffic as I don't know what else I can do.
I moved into my flat two years ago, The first Christmas I was there a parcel arrived with my address on it, I opened it because it did not have a name on it at all, Just my full address, Thought it was for me, It wasn't, It was full of wrapped Christmas gifts, a few cards and a letter, I opened the letter to see who it was for etc and it did not have a return address on the letter, There was cash inside the letter. It was from a grandmother to her daughter and grandkids. I still have all this unopened, apart from the letter. Grandmother wrote her husband wasn't well and she was trying to let them all know.
Brought it up with post office, I then had a death in my family and forgot about it. Over time more letters have been arriving and I saw the writing was the same, I put them to one side with the gifts etc. Christmas came around again and the same thing happened, Gifts etc.
There is a street not far from me (made up names) so say my street is called Highgate Drive, the other street would be Highgate Road, I went there to see if they knew any of the names as I thought it had been delivered to me instead of them, they had no idea and it wasn't for them.
I dropped them off at the post office and told them there was no return addresses and they were not for me.
More stuff keeps arriving so I opened a few of them again to see if any return address and there isn't one. Grandmother has now said grandad has passed away and how upset she is, and she just wants a hug from her grandkids.
Previous person who lived here left and nobody knows where she moved to so I have no way of contacting her. Her name is the same name as the daughter in the letters so they are for her, she had two kids also. She clearly hasn't told her mother where she is now living.
I have the name of the grandmother, daughter and two kids, Also know name of grans dog but for privacy of the family didn't want to post online.
What do I do?
