Then the years go on, the kid becomes an adult and begins cooking for themselves. The first meal they make for someone else they realize (1) how difficult it is to estimate when a meal will be done (2) how much work goes into cooking, especially for a whole family and (3) how hurtful and disruptive it is when the person you’re cooking for decides they’d rather eat your food when it’s cold and gross and everyone else has already finished eating and are trying to clean up. And that’s not even incorporating the social elements of family dinner time the kid is eschewing. I didn’t understand as a kid why my parents were so adamant about family dinner, but as an adult it’s something I’m really glad they enforced.
