When Juliet does not jump for joy at the announcement that she will marry Paris in a week's time, Lord Capulet is furious with Juliet.
Lord Capulet is incensed that Juliet is not complacently accepting his commands as he has always expected her to do. Until this point in the play, Juliet has always complied with her parent's wishes.
Lord Capulet tells her he will throw her to the streets and cause her to be a street urchin if she does not obey him. He is borderline physically abusive towards her, and most certainly verbally abusive to her, calling her names such as, "carrion" and "baggage". He is threatening, as well, when he tells her he will do whatever is necessary to get her to the church.
This shows that parent-child relations were not close. Children were meant to be obedient and subservient to their parent's wishes. It was not acceptable to show outward defiance.
