Of course, though, had Romeo not had such depths of feeling, the love he shared with Juliet would never have existed in the first place.
Among his friends, especially while bantering with Mercutio, Romeo shows glimpses of his social persona. He is intelligent, quick-witted, fond of verbal jousting (particularly about sex), loyal, and unafraid of danger.
Juliet .
Having not quite reached her fourteenth birthday, Juliet is of an age that stands on the border between immaturity and maturity. At the play's beginning however she seems merely an obedient, sheltered, nave child. Though many girls her age "including her mother "get married, Juliet has not given the subject any thought. When Lady Capulet mentions Paris's interest in marrying Juliet, Juliet dutifully responds that she will try to see if she can love him, a response that seems childish in its obedience and in its immature conception of love. Juliet seems to have no friends her own age, and she is not comfortable talking about sex (as seen in her discomfort when the Nurse goes on and on about a sexual joke at Juliet's expense in Act I, scene iii).
Juliet gives glimpses of her determination, strength, and sober-mindedness, in her earliest scenes, and offers a preview of the woman she will become during the five-day span of Romeo and Juliet. While Lady Capulet proves unable to quiet the Nurse, Juliet succeeds with one word (also in Act I, scene iii). In addition, even in Juliet's dutiful acquiescence to try to love Paris, there is some seed of steely determination. Juliet promises to consider Paris as a possible husband to the precise degree her mother desires. While an outward show of obedience, such a statement can also be read as a refusal through passivity. Juliet will accede to her mother's wishes, but she will not go out of her way to fall in love with Paris.
Juliet's first meeting with Romeo propels her full-force toward adulthood.
