JULIET: Don't swear by the moon. The moon is always changing. Each month it shifts its position in the sky.
I don't want your love to be that inconstant, too.
ROMEO: What should I swear by?
JULIET: Don't swear at all. But if you must swear, then swear by your gracious self, which is the god I worship like an idol.
ROMEO: If my heart's dear love—
JULIET: Well, don't swear. Although you bring me joy, I take no joy in this exchange of promises tonight. It's too rash, too sudden, like lightning, which flashes and then disappears before you can say "it's lightning!"
Good night, my sweet. Our love now is like a flower bud, which the summer air may ripen into a beautiful flower by the next time we meet.
I hope you enjoy the same sweet peace and rest I feel in my heart.
ROMEO: Oh, are you going to leave me so unsatisfied?
