We do discuss the meal plan, as a family, before I go to the grocery store. They do get to help decide the menu and I don't serve them food that I know they don't like.
Not really trying to accomplish anything. That is how we were brought up. Our families are southern, blue collar, low-middle class.
The men work hard to buy the food, the women work hard to cook the food, don't wear your hat at the table, and don't let Grandaddy see you throwing food out. smile
