I received a letter addressed to Eileen yesterday. I know that correspondence of all sorts, so addressed - much of it marketing junk - will probably keep coming for a while, but this one looked a bit different. It was franked by the US Mail and had come from Irvine CA.
It turned out to be from the manufacturers of the aortic valve that Eileen received eight days before she died, advising that she had been added to their registry and enclosing a card to be carried.
I emailed them, and had a reply, expressing condolences within a couple of hours.
