so you can die for your country at 18 but you can't drive a corvette at 20 WTF.
so if you were 18 and in a fox hole being shot at and your friend says i bet you wont stick your head up are you going to do it, NO, your not. you know better you know what the consequences are. the same goes for everyone everytime they get in a car. it doesn't matter what kind of car what matters is your experience with the car and your ability to handle it. a friends influence is usually just an excuse to do something you already wanted to do but knew you shouldn't.
i seriously hope thats not the mentality you have when you raise your children, hiding everything from them, not letting them do anything that might hurt them or doing it for them, they are going to be a lazy spoiled brat that expects everything handed to them. and they are not going to have any skills or decision making abilities. people are not born with common sense it's a developmental process from all your past experiences.
hiding it doesn't solve the problem. humans by nature are risk takers, they are the ones that survive. you can't always make the right decision but you can learn from your mistakes. the worst thing about human nature is their inability to learn from other peoples mistakes.
choice and influences are a part of life what you learn from them is what makes you, you.
never being presented with the choice is the worst thing that could happen.
human beings were not meant to live in bubbles their entire life.
the younger you start the better you will be.
