How to treat some rural people with leftovers?

In the early years of the past, that is, those hard times, there were almost no leftovers in our rural hometown, and all the leftovers were cooked in pots, pans and bowls. In other words, in rural families, there is no food left at all, no food left. In those difficult days, it's good to fill your stomach, good, good. I'm not afraid of jokes. At that time, every meal in our family would be swept away. Although I didn't feel hungry at that time, there was basically no leftovers in our house. Later, after the rural life was better, there were leftovers. When there is no refrigerator in the countryside, the leftovers in the countryside are also leftovers from the last meal and will never be wasted. Unless the leftovers are sour, give them to chickens, ducks, geese, pigs and dogs. Later, every family in the countryside had a refrigerator, and the leftovers were put in the refrigerator. Although I have been in the city for many years now, there will still be leftovers, so I am still not afraid of others laughing at me. I never throw away leftovers. It is no problem to put the leftovers in the refrigerator and eat them at the next meal. Don't say that I will live, and don't say that I have experienced their difficulties.
