Yet still they have all the right of adulthood. I have a counsin who recently turned 60 and she is a woman with VERY low cognitive abilities, almost borderline mentally challenged. Yet she still has all the rights of adulthood, like any other adult. Danielle Steel describes in turn in her biography of her highly gifted, currently deceased son Nick Traina, entitled "His Bright Light" that as a twelve year old he managed to convince some lady who didn't know him, that he was actually an adult guy of 21 (I believe that also a Harvard student) with some hormonal problems causing him to still look like a kid. Said woman believed him because as she later told his mom, "It's enough to talk to Nick to know he's an adult man".

So it depends on a teen. I saw cases of 12-14 year olds online who talked in discussions (so also, as we can guess, also thought) like any other adults. Anyway, I once participated in an online discussion - as an actually adult woman of 26 - and some creepy lady said to her buddies from the message board (I was new on there) that "a girl of 26 doesn't write like that" so I'm a much older troll, pretending I was a young woman - sorry; a GIRL
Great that the limitations concerning one's power over their own life don't last long and even as a teenager, you have some such rights. Like: at 16 you can get married (as a girl at least) here in Poland and if you do, you instantly get all the rights of adulthood, even after a divorce or if you became a widow the next day after your wedding. At 15 you can have legal sex with adults - and in some countries, the age of consent is even lower (like 14 in Austria or 13 in Spain). At 13 you can also decide in the court with which parent you want to stay after their divorce and so on. To the best of my knowledge, in Texas you can legally get married (with the court's permission, of course) at 14.
