That was not the explanation I was expecting:
We ran into our letter carrier this afternoon, on our way out to go get apples and such. She had gotten my note. She had gotten a lot of notes, because nobody in the building had gotten their mail in weeks.
The building key that the postal service has stopped working a few weeks ago; they have made numerous calls to building management. We got lucky today because someone left the door propped open with a traffic cone, and when I talked to her the letter carrier was in the process of delivering a lot of mail. I told her that I'm often home during the day, and if she can't get in, she should buzz my apartment.
We have received, among other things, at least two bills; a check from one of my freelance clients, which I suspect may be too crumpled to deposit with the phone app; and a Rosh Hashanah card from my aunt Lea. I may have to look for a partner credit union that will actually let me deposit a check; when I tried last year, I found one ATM out of order and one that wouldn't actually take deposits from members of other credit unions.
(Also, I just ate a fine ripe tomato, and I have a bag of my favorite apples, and more grapes and raspberries.)
