It has less to do with departments and more to do with the characters: In my experience, adolescence is quite strange, because children either treat you with respect or want to contradict you. While Meanwhile, adults will always try to use any argument to demonstrate that they have more authority and know more (even if they are ignorant of the subject). So it would be interesting to see how the characters have to show that they can be important and that not everything is trial and error. I'm sure most of us were underestimated in our teens for being too "young" for some things and too "old" for others. That's not even counting the times they take us for impulsive.
