In Act III, Scene 3 of Shakespeare's play "Romeo and Juliet," Friar Laurence gives Romeo three reasons to show that he should be happy despite his banishment:
Romeo is still alive: Friar Laurence reminds Romeo that he is fortunate to be alive, as the Prince had initially sentenced him to death for killing Tybalt. Therefore, Romeo should be grateful that he is still alive and has the opportunity to see his wife again someday.
Romeo and Juliet's love is true: Friar Laurence believes that Romeo should be happy because he and Juliet truly love each other. He sees their love as a rare and precious thing, and reminds Romeo that they will eventually be reunited.
The banishment is a lesser punishment than death: Friar Laurence argues that Romeo's banishment is a lesser punishment than the death penalty he was originally given. He believes that Romeo should take comfort in the fact that he can still live his life, even though it will be without Juliet by his side for a time.
Overall, Friar Laurence is trying to help Romeo see that his situation is not as hopeless as it may seem, and that he should find solace in the fact that he is still alive, his love for Juliet is true, and his punishment could have been much worse.
