“Y’know, I’d be thrilled if our mail carrier could read and speak Englishfunny you should mention that...”
I had a postman deliver some mail from another BLOCK to my house...I caught up with him and this genius couldn’t even read the street sign!
You'd be shocked and surprised how easy that is to do, even as an experienced mail carrier. You, too, would do it. I guarantee it. I know of no one that can maintain full mental awareness of every second of their day. One slip-up and you've put mail in the wrong box, and someone is complaining on the internet.
