Milkman home delivery in glass milk bottles died out in the 1950's. Reason:

1. Refrigerators replaced ice boxes. Thus milk could stay fresher longer.
2. Most of the population moved to the cities where they could buy milk from the local store for less money.
3. After WWII, most of the population got a car so they could drive to the store.
4. The glass milk bottle made the milk cost ineffective vs plastic or cardboard containers.

Prior to that, if you wanted a daily quart of milk it was because you couldn't keep at least two cows.

Therefore if you are the milkman's kid, you're collecting social security.

Because women also deliver mail, the word "postman" is considered sexist and was replaced by the phrase "letter carrier." There is no telling which gender delivers your mail. I used to get my mail direct from a post mistress, who snarled over the term "mistress." She was married.

Conclusion: you've aged well.

Here they rotate the letter carrier's routes so they know all the routes. Therefore I might get whatever gender is available to deliver my mail. Does it work that way for you?

@WonderWartHog99 They bid the routes, so 5 days a week I have the same person,
