Actually Welcome to the concept of Drama
Step-by-step explanation:
Generally speaking, Juliet simply does not seem very interested in marriage at all, let alone marriage to the Count Paris, a man about which she knows little, aside from his position and that he will attend the Capulets' party that night. Juliet's mother and nurse have a great deal more to say about Count Paris's interest in Juliet than Juliet has to say about Count Paris, indicating her lack of enthusiasm for marriage.
Juliet basically tells her mother that she's never even really thought about marriage, that it hasn't even entered her dreams. She then dutifully agrees to "look" at the Count and see if she thinks she might be able to like him, but, if she does like him, she will go no further with her liking than her parents' consent would permit her.
The brevity of her responses shows Juliet isn't really interested, but her obedience to her parents is clear.
