There should be an upside/down question mark before the word "Son" but I don't know how to do that on the computer.
The question is, "Are you (you-all) rich?" This is another 1950s Mexico story.
In our cement-block rented house on the Pacific coast, the "kitchen" was just a bare room separated from the living room/sleeping room plus bath, by a heavy wooden door.
The kitchen did have running water and sink, which was very convenient. There was no refrigeration. I cooked on a kerosene stove and could write a book (which would appeal to a very small audience) on how to prepare food without tainting the food with a kerosene smell and taste.
Every morning I walked to the nearby small town to buy groceries for the day. I also purchased kerosene, which I carried in a separate leather bag so as not to taint my groceries.
One of my everyday grocery items was a small can of evaporated milk and a little packet of coffee wrapped in a bit of newspaper. At breakfast we had the coffee with about half the milk. Then I placed the can with remaining milk in the kitchen window sill. By noon it had soured. No problem. An noon I made sour-milk biscuits.
The window in my kitchen looked out on a pasture where a couple of horses grazed. Immediately in front of the window was a deep horse trough filled with fresh water. All this belonged to our landlord.
One mid-morning a woman who may have been in her '20s or '30s, approached my kitchen window with two children who were grammar-school age. She asked me for permission to bathe her children in the horse trough. I said yes, although it wasn't really my horse trough.
As she bathed the children and the water got soapy, I began to worry. Soapy water couldn't be good for the livestock. I imagined myself spending the rest of the day dipping out the soapy water and replacing it with fresh.
But she did that herself. When she had finished, the young mother came to our kitchen window to thank me. She also asked, "Son rico?" "Are you rich?"
I replied "no". She pointed to the open can of evaporated milk. Proof positive. And she said, "Son rico." (You are rich.)
I had to admit she made her point.
