What is an example of how Lord Capulet is hasty in Romeo and Juliet. (I already have the one about his setting the marriage date so soon but I can not find another one.)
Lord Capulet is impetuous in the beginning of Shakespeare's Romeo and Juliet.
In the opening scene of Act I, Lord Capulet hears the quarrel among the servants of the two houses of Montague and Capulet. Although he is still in his gown and not dressed for any kind of conflict, he immediately calls for his sword. Moreover, he does this because he wants to enter into the fight despite his knowing that his family and the Montagues have engaged previously in three civil brawls and his wife's admonitions at the moment.
What noise is this? Give me my long sword, ho! (1.1.65)
As he continues to call for his long sword, Lady Capulet says he needs a crutch more than he needs a sword,
A crutch, a crutch! why call you for a sword? (1.1.66)
Still, Capulet is so angered that he does not think about his age and physical condition, nor does he consider that his family is not supposed to engage with the Montagues. He ignores the cries of the citizens, as well, who shout, "Down with the Capulets! down with the Montagues!" because they are tired of the two families' feuding with one another.
