It's a perfect sonnet.
14 lines. 3 stanzas in ABAB rhyme, and a rhyming couplet at the end.
It starts off with each of them speaking a whole stanza. Romeo offering up a self depreciating metaphor (a pilgrim at a holy shrine, sinful for wanting to place a kiss on her hand), and Juliet returning it (it's not a sin for a pilgrim to touch the hands of a saint. Pilgrims and the saints hands can touch. )
Then they share a quatraine, keeping the rhyme and rhythm steady, the flirting turning even more overt. (Saints and pilgrims both have lips, yeah? Well, sure, for prayer. Well if a pilgrims hand can touch a saints hand, then their lips...)
Then they each speak half a couplet (the saints dont make the first move, but if its a prayer....well, here I am, praying....), and share their first kiss.
It's flirty and silly and a little irreverent, and they become more and more in sync as they speak.
This is a heightened, fantastical, almost reality bending moment. This is a moment where two lonely teenagers, one who is having her future decided without her and the other fresh from an unrequited rejection, feel the world shift around them.
And the foreshadowing sits at the end of stanza 3. This is an act of faith, but if it cannot be, it will turn to despair.
And I just. The craft of it. The poetry of it. How the form and the rhythm mirror the metaphor and mirror the emotion of it.
