Even usps can’t deliver to rural addresses. They deliver to line of boxes at the highway intersection which get ran over or broken into monthly.
Luxury. I live in a PO Box-only zip code. Heaven help you if the USPS gets ahold of anything addressed to your street addresses, you’ll never receive it.








Other people have touched on it, but I really want to emphasize how completely ordinary it used to be to go to someone’s house uninvited, unannounced. Well into the telephone age, it was regularly done. And you were expected to always invite them in.
If you wanted to appear to be an at least minimally functional member of society, you would keep some sort of snack food, a cake, cookies, scones, muffins, et cetera, constantly in stock so that you could offer refreshments to literally any person anyone in your household had ever met in their lives, showing up at your door at absolutely any time.
Refreshments were the bare minimum. The further back you go, the more likely your guests were going to want to live with you for a while.
