As has been said, I find it baffling that people continue to send cards to people they've had nothing to do with for a decade or more.
We (DH and I and the DC) continued to receive a Christmas card from a guy DH worked with back in the mid 1990s. He worked with him from 1994 to 1998 when the guy (Andy) left...
Even by 2008 the cards were still coming to our house from him and his wife, and he hadn't seen the bloke since 1998. (He got married in 1996,) Always 'Merry Christmas Zov, Mr Zov, and the kids, from Andy and Diane.' DH saw Andy with 5 or 6 other blokes from the workplace about 6 times over the first year for a drink down the pub, but then by mid 1999 there was no contact. Nothing bad, just sorta drifted...
So he had lost touch by 1999, and we didn't know their address, so couldn't send a Christmas card back! (No social media then!)
We left the home we had lived in since the mid 1990s in 2008/2009, and the Christmas cards from them kept coming right up to when we left, even though we hadn't given them one in an entire decade - because we didn't know their address! Even now in 2025 it wouldn't surprise me if they were still sending them to that old addrerss that we left one and a half decades ago!!
