LORD CAPULET Welcome, gentlemen! I have seen the day
Lord Capulet's musings about the good ol' days reminds us that youth and love are fleeting. This occurs just before Romeo and Juliet's first meeting, where they fall head over heels in love (at first sight). It seems like Lord Capulet's reminiscence is Shakespeare's way of preparing us for the short-lived (no pun intended) romance between Romeo and Juliet.

Here's a good look into the future: Romeo and Juliet might be in l-o-v-e now, but how would they feel after a decade and a couple of kids? Probably not spouting so much love poetry.

Juliet's right—much better to swear by the stars, which at least are constant. (If equally cliché.)
