[PH] Parents don't get teaching moments if adult sibling in house

I have this issue too. In my current game's story, I've got something of a foster family situation. Several unrelated kids/teens, a caring, adult woman who has all the parenting skills, and the sort of useless, aloof husband, who always just fixes things up around the house and cares for some farm animals. He has almost no parenting skills and therefore very few options for teaching moments. Yet when the kids go to school, it's always him who gets phone calls about their behavior. I wondered if it has something to do with the fact that he's the first adult sim in the character list on the UI; maybe it defaults to the first available adult on the list.
