What do my children do when I tell them to do their chores?
I'm just curious what my skyrim children are doing when I tell them to do chores. They knock stuff over in the house sometimes but they don't clean it so what are they up to?
They will wish the floor. Child labour!
"Go do your chores, (Name)." — You can ask your child to do chores; they will begin to sweep the floor unwillingly.
I experienced back talking from some children, this just happens. In the case of back talk, they won't do anything.
Knocking things is, as @Ben mentioned, a poor collision detection.
