Sometimes we teenagers have to be adults and other times we are children. On the bus for example we have to pay adult price when we are sixteen years old, but that's almost the only time we are allowed to be adults. Well, not exactly, you always get to hear from your parents that you have to act like an adult when you have agreements with your siblings. “Your the oldest one, you ought to know better! Don't be so stubborn”, your parents shout while your sister is sitting on your back, pulling your hair. And all this because she wants to borrow some make up. “Stubborn, who is the stubborn one here?”, you think while you get up and go to get her some make up. She wins again, only because you are expected to give in, and that is what you do.
In school you have to be part grow-up and part child. You have to be grown up in the way you act, and preferably a bit in the way you express yourself. But this is also a place where you can be a child, or maybe more likely a teenager. As you go from elementary school to high school you have to start behaving better and acting more and more like a grown up. There is quite a bit of changes going from a child to a teenager. As a child it didn't matter that much if you didn't say “thank you” after a meal or maybe forgot to flush the toilet after yourself, but if you do something like that now it would be looked upon as rude and impolite. That is because you are expected to know better when you are older. As you grow up you get more and more responsibility. You can for example get more responsibility with your own money, but it is also expected that you'll use it wisely. Or you can be given the responsibility of taking care of your siblings, but also then there are expectations, expectations that you will take good care of them and not do anything crazy. You also get much more responsibility over your self, if you go out for a weekend your parents count on you taking care of your self and not doing anything stupid.
