I believe your evaluation is completely off base. A 17-year-old is not a juvenile. He is one year away from being able to serve as a soldier in the strictest of environments, and vote. I was a private pilot at age 17 and devoted much of my time to preparing for college. You would have nonchalance be the dominating attitude toward unacceptable tantrums, and more restraints added. This would only serve to miscommunicate that misbehavior is not taken seriously, and better restraints would merely demonstrate that absolute control is the ultimate, easy, and regrettable solution. IMO, this would create more hostility, not less. A person who is misbehaving needs to be told and understand that their actions are a disappointment, not just chained up until he gets over it. “In short”, employing discipline vs. control are two very different approaches, the former making a much more constructive impression.
