It’s still not the kid’s fault if they were brought up to tolerate and play emotional games against family members.
Having kids myself and listening to them describe their fellow students’ situations at home, or even how we observe acquaintance’s kids act and how it mirrors parental behaviors, you can bet your ass that they learn from how their parents are acting and what they’re allowed to get away with.
You could do the same thing with a painting and a dim light. Just wouldn’t move. Assuming there are ”fake window” screen saver things for projectors.
