No, She simply is there to serve the role neede for the plot. You can see this when Lady Capulet speaks to Julieet of a marriage to Paris. She has little to no emotion.
Lady Capulet is usually considered a flat character in "Romeo and Juliet" because she does not undergo significant development or change throughout the play. She is depicted as primarily motivated by her desire for social status and her relationship with her husband, rather than showing a complex and multi-dimensional personality.
lady Capulet is a foli of the nurse and she's a flat character.
Your question is unclear. Is Duty a different play from Romeo and Juliet which also has a character called Lady Capulet? (actually, the character in Romeo and Juliet was not called Lady Capulet in Shakespeare's time--since Capulet was no lord, she could not be a lady. She is called the much simpler "Mother".)
The Nurse foils the character of Juliet's mother, Lady Capulet. As her mother, Lady Capulet should know everything that there is about her daughter; she should know how old she is and her innermost feelings. However, Lady Capulet knows neither. Early on in Act 1, Lady Capulet is unsure of Juliet's age and the Nurse has an extended speech in which she explains to Juliet's mother how she knows how old Juliet is better than her mother does. Additionally, throughout the play, it is the Nurse that Juliet goes to for advice and assistance, not her mother.
Yes, whenever there is a scene in the Capulet's house, Juliet is usually a round somewhere.
Lady Capulet is busy preparing for the Capulet's masquerade ball.
Tybalt is a member of the Capulet family. A nephew of Lord and Lady Capulet. He is also the character who kills Mercutio and is himself slain by Romeo's hand.
Tybalt is associated with the Capulets, and he thinks of himself as a Capulet, but he is actually not a Capulet at all. He is the son of Lady Capulet's brother, and Lady Capulet is only a Capulet by marriage. That is why it is Lady Capulet, and not Lord Capulet, who is so furious with Romeo after he kills Tybalt.
Lady Capulet imagines that Juliet is crying because Tybalt, Lady Capulet's kinsman and consequently also Juliet's, is dead.
she was nice to other people, but she was very mean to lord Capulet.
I don't know about Lord Capulet, but I know for certain that Lady Capulet is fairly young. She tells Juliet that she was about her age when she was had her. This means that Lady Capulet is 26. I guess due to stress she can look a few years older though. For Capulet, I guess you can say that he is well dressed and groomed. He is from a wealthy family after all. The same applies to Lady Capulet.
Lady Capulet tells Juliet that she has arranged for her to marry Paris.
They are only referred to as Capulet and Lady Capulet.
