I confess that for the most part, I rarely put much effort into controlling the rest of the household. I have a main sim that I usually have some sort of goals for. The others in the household I only really touch if they're neglecting their own needs or if I need something done and the main sim is otherwise occupied. There is a LOT of autonomy in my sim homes, mostly because it is much more fun for me to just roll with whatever happens. I embrace the random! I love the random!
