In William Shakespeare's play "Romeo and Juliet," Friar Lawrence and Lord Capulet do not act like children. In fact, both characters are portrayed as adults who are respected members of society. Friar Lawrence is a wise and thoughtful religious leader who tries to help Romeo and Juliet navigate their difficult situation, and Lord Capulet is a powerful and influential nobleman who is concerned about the reputation and well-being of his family. Neither character displays the immaturity or lack of responsibility that is typically associated with children.
