True story (as true as any story passed through two or three generations of Creoles):*
The neighbors were a typical big New Orleans family, eight or so kids spanning a range of ages. The mother was nursing the baby. One of younger walking/talking ones came up and stared at the feeding infant, seeming curious/perplexed. The mother explained, "I'm giving him milk." The young walker/talker paused, pondering, then asked, "Is there coffee in the other one?"
* I was reminded of this story by my dad, when it came up that the girls have started drinking coffee-milk: warm milk, a generous spoon of sugar, and the teeniest-tiniest few drops of coffee.
