Had Juliet been older, do you think she would have done the same things she did in the play?

If juliet was older I think that she would have acted worse than she did when she was younger. why, because she would have knew more stuff, and she could do more. And, since she is older she could have more legal things, and purchase things that she couldnt since she was a kid. What I mean is that she could have probably got the poison herself instead of waiting for Friar to get it for her, and she probably would have went to Romeo herself instead of him coming to her. All I'm saying is that she could have made alot of other decisions if she was older.
