Oh Romeo why do you have to be a Montague, please change your name, who cares about your father, and if you don't change your name I will.
I wish you had my bones, and I had your news. Come on now, I beg you, speak, good Nurse, speak.
Jesu, what haste! Can you not stay awhile? Do you not see that I am out of breath?
So smile the heavens upon this holy act That after-hours with sorrow chide us not.
After meeting Juliet at the Capulet party both Romeo and Juliet are intensely in love, this leads to Juliet talking on the balcony about Romeo when Romeo is near her which she doesn't know.

After that, Romeo and Juliet converse about how unsafe it is for Romeo to be there and how if he gets caught, he will get murdered.
