There needs to be more consequences for teens, adolescents and kids.. like grounding, scolding, warnings, taking phones away, forced house chores when not behaving. Schools calling parents when skipping classes. This would make teen gameplay soooo much more better.
When a teenager is outside after 10 pm, the parents should feel concerned.. they should panic call the teens (teens can choose to ignore calls/text), and after they get home they discipline them and ask “where where you?!” 
and if the teens consistently do this, it could lead to a grounding or a harsh scold.
Also, when siblings start to hate each other the parents need to notice it.. there could be a family talk where they sit at the table and the parents would talk about their relationship and try to fix things between the siblings and again discipline them.
When teens sneak out of the house or skip school to hangout instead of going to classes. There need to be some type of challenge where they need to be careful that a family member don’t caught them somewhere outside.. and if they get caught there’s gonna be real consequences.. and the person that caught them would be angry or disappointed (depending on their traits and personality). When a teenager zoi sees their parent/older sibling.. there needs to be some type of physical reaction. The teen will have a shocking reaction and jump back seeing their caretaker.. and the caretaker would have a angry reaction and walk towards them.
For example: if a teenager keeps annoying their younger siblings, there need to be an option for the parents to “call them out” and tell them to behave better. Because i see that in my gameplay that the teens and kids just come and annoy each other to form a fight lol.. i would like the parents to discipline them on that. Hope you see this Kjun
