Similarities
Both Romeo and Juliet are devastated by the news of Romeo's banishment. They both express their grief through tears, lamentations, and despair. They both feel a sense of hopelessness and loss, as if their world has been turned upside down. They also both blame themselves for Romeo's punishment, feeling that they could have done something to prevent it.
Differences
However, their reactions also differ in some ways. Romeo is more impulsive and emotional in his reaction, while Juliet is more composed and rational. Romeo immediately reacts with anger and frustration, lashing out at Friar Lawrence for not being able to help him. He is also more prone to taking drastic measures, such as attempting to kill himself. Juliet, on the other hand, is more patient and willing to wait for a solution. She is more focused on finding a way to be with Romeo again, and she is willing to consider unconventional or risky options, such as faking her death.
