Start “home economics” school with them. Laundry, cleaning, cooking, how to change a diaper, comfort a baby, soothe a toddler, what's involved in caring for pets, budgeting for food, keeping track of maintenance schedules for humans, pets, cars and machines. Engage with guests, be a good host, etc. Know when and how to tell someone to GTFO of the house (racist or misogynistic speech, etc.) Every kid needs to learn the art and science of home management. Look for and point out examples in books and movies of good home science skills.

Have dinner guests sign the under side of the dining room table. Let the kids’ friends sign too - or have their own version of a guestbook - the inside of a cabinet or the basement door, etc.
To paraphrase Ted Lasso, it’s the people who think they’ve got it all figured out who delight in judging people and events. It’s better to be open minded, ask questions. Be curious, not judgmental.
