After reading Shakespeare's version of the play Romeo and Juliet, I have come to the conclusion that Juliet Capulet, one of the plays co-stars, was a mature person. This conclusion is obvious to any reader with a keen insight for spotting those characteristics which make up a good moral fiber in a person. No sane reader could disagree with this conclusion.
Firstly, Juliet was independent she was capable of making her own decisions. This is shown in the fact that she ran around with Romeo Montague, a member of a family with which her own family had a feud. But she disregarded
common sense what others thought was best, and took the situation into her own hands (getting herself into a sticky mess) to show that she had a mind of her own (and because Romeo was cute).
Secondly, she had great intelligence. Only a person with a brilliant mind could work out a scheme so complex that it could manage to ultimately result in the deaths of almost all of the characters in the play.
Thirdly, and, possibly, most important, was Juliet's sense of responsibility to the good of the world. This is evidenced in the fact that, at the end of the play, she killed herself.
Such mature actions can only point to the fact that Juliet was mature in virtually every way.
