So I see that this is still not fixed yet?
I just brought my sim over to his mom's house with his fiancee and kids, and tried to have him cook something for everyone to eat, and his mom yelled at him with the "react to inappropriate behavior." They have a 100% relationship, by the way. She didn't autonomously cook anything for them and the grandkids were hungry, so what else is he supposed to do? What grandmother wouldn't want her grandkids to be fed? He can't ask her to cook something for them. He can't ask if he's allowed to cook. So everybody just starves or they go home? Or they run halfway across the neighborhood and use a public grill and waste a ton of time?
It just feels so anti-social. It's his mom's house, his childhood home, and his kids are hungry. How is that even inappropriate behavior?
There NEEDS to be different rules for close family members. This is silly.
