It's not that hard to cook Sunday dinner, not for grown adults to be fighting about it. It's not hard at all actually. In fact, it's easier than ever if measured in the time it takes.
Grandma was cooking for 6 kids, not 1.5 kids and a dog.
Microwave, oven, induction stove top, air fryer, crockpot. Modern manufacturing has made these appliances 10x cheaper, Amazon has made them readily available. Order your groceries online, curbside pick-up, don't even have to go in the store.
No, this isn't about cooking it's about being defiant and combative. It's about not wanting to be led.
If it isn't Sunday dinner, you'll get pushback on laundry or cleaning. They got roombas. Clothes aren't line-dried or basin-washed. The dryer comes with wrinkle-away. I can't remember the last time I bought a can of starch or used an iron.
Man said Sunday dinner. Not
Sunday-Monday-Tuesday-Wednesday-Thursday-Friday-Saturdaaaaay. Just Sunday.
I don't wanna hear it.
