Sometimes people should just listen. I didn't expect the clerk at the post office window to solve my problem, but I did want to tell him what my problem was. He didn't let me, so I'm going to tell you instead.
As you know (I love saying that), I never buy anything for myself in even-numbered months (like August, as a random example). So on the last day of July I went on a bit of an online spending spree. Nothing elaborate, just a book and a video. That's not really a spree, except in the sense that I won't be buying anything else until the first of September.
My last package should have been delivered by my mail carrier yesterday. Instead, she left me a note in the mailbox saying how "sorry" she was that she missed me, and that I could pick up the package at the local post office this morning, any time after ten. So I took the slip to the post office this morning and handed it to the clerk.
Now, I know that my carrier didn't try to bring the package to my door to get a signature. I know that because I was home all afternoon and found the notice in the mailbox the last time I checked. It makes me believe that it wasn't my regular carrier, because she always comes to my door when she has something that doesn't fit in the box.
