Today is the National Thank A Postal Employee Day.
I retired from the Postal Service after 33 years. I still can't sleep through the night because of a torn rotator cuff pain and carpal tunnel.... but that is OK. I had the pleasure of serving you (me rolling my eyes).
You are welcome, thank nothing of it.
I Googled Postal and mail and all that kind of stuff looking for some kind of visual image and I came across the above hiring sign for the Pony Express. It says "Orphans preferred". It also said, "not over 18". It also said being wiry & skinny was a requirement. That was before my time.
