Act 1. Scene 5 = the most gorgeous flirting scene of all time.
It's not that Romeo is just wooing Juliet. He's giving her material-- which allows her to dish it right back. (The 14 lines spoken between when they meet and when they kiss equal a perfect sonnet-- which means they are rhyming off of each other, and, at the very end... with each other.)
Good flirting requires a good amount of fearlessness*. Romeo just grabs her hand. It's impolite, but he's unafraid because he's about to compare her to a saint, and then a shrine, and then he's going to have the guts to say kissing is like praying.
*(which is really an extreme kind of vulnerability)
