Because the Nurse is the most plausible person to enter her bedroom and wake her up. You note in Act II it is the nurse who supervises the bedroom, whose calls Juliet answers from her balcony. Again in Act III it is the Nurse who alerts Juliet that her mother is on her way, and Romeo had better scoot. Her parents never enter unless the Nurse has seen her previously.
It is Juliet's nurse who interrupts Juliet's and Romeo's conversation on the balcony. She calls Juliet back inside, urging her to come back to her room.
The dramatic purpose of the nurse entering in this scene is to let you know that Lady Capulet was on her way to see Juliet.
The Nurse probably does not sleep in the same room as Juliet anyway. Juliet is able to stand talking on her balcony without being observed by the nurse who must call for her. The Nurse is able to leave Juliet and Romeo to sleep together without attracting any attention in the household, since she is not there when they wake up. Likewise she is left alone on the night before her intended marriage to Paris. The Nurse would probably have been flitting around fussing over what kind of wedding dress Juliet should wear, but at the beginning of Act IV Scene III Juliet tells her to go away so Juliet can pray.
In act 4 scene 5, Juliet's nurse walks into Juliet's room to get her ready to marry Paris, but Juliet took the potion to make her "dead". the scene is basically Capulet, Lady Capulet, Nurse, and Paris talking about how sad they are that Juliet's dead. and saying goodbye.
The nurse isn't allowed to stay in Juliet's room the night before Juliet's wedding to Paris, because Juliet has to take the "medecine" the priest gave her that will permit Juliet to only sleep longer andnot die. Juliet takes that "medecine" because she doesn't want to marry Paris, but wants to be with Romeo. As a consequence, she fakes her own death. In order to take the "medecine" unnoticed, she has to be alone in her room the night before the wedding. So, no nurse allowed to stay.
The Nurse. The Nurse discovers Juliet after when she goes to wake her up to tell her Paris was waiting for her downstairs. She finds Juliet apparently dead (actually in a deep sleep after taking the potion) then runs back to get Lady Capulet.
In the play he uses a rope ladder that the nurse brings to Juliet's balcony for him. In the movie he just climbs up a tree.
She plans to use it as a ladder to get Romeo into her room and "tie up the marriage" (During this time, the marriage would not be complete until the lovers had sex). Of course, this is not actually "said" in the play, but we can say that it happened between Act III Scene 3 and Act III Scene 5, since in the end Scene 3 Romeo runs to an unknown place and at the start of Scene 5 he is seen with Juliet early in the morning.
Well in act 3 scene 2 Juliet awaits in her room to see romeo climb the ladder and come to see her. But the nurse comes in and tells her that Tybalt, her cousin, has been killed and Romeo has been banished. Those are the two reasons. *Tybalt being killed *Romeo being banished
In Act 4, Scene 5 of Romeo and Juliet, the Capulets are preparing for Juliet's wedding to Paris. However, the event takes a tragic turn when Juliet is found seemingly dead in her room.
Most of the dialogue in the "balcony scene" takes place at the window in Juliet's room. Only the final line is on the actual balcony.
Act 3 scene 5 of Romeo and Juliet is set in Juliet's room. Romeo is leaving for his exile and Juliet is upset over the separation. Lady Capulet then comes into Juliet's room and informs her that she will be marrying Paris. The conflict is that Juliet's parents are forcing her to marry Paris and she is already married to Romeo.
