Adolescent or not, though, I sure enjoyed reading it this time through. Romeo and Juliet's first meeting, for example, all by itself validates the romantic comedy genre.
[To JULIET] If I profane with my unworthiest hand
This holy shrine, the gentle ﬁne is this:
My lips, two blushing pilgrims, ready stand
To smooth that rough touch with a tender kiss.
Good pilgrim, you do wrong your hand too much,
Which mannerly devotion shows in this;
For saints have hands that pilgrims' hands do touch,
And palm to palm is holy palmers' kiss.
Have not saints lips, and holy palmers too?
Ay, pilgrim, lips that they must use in prayer.
That is some searingly saucy banter, there. "Ay, pilgrim, lips that they must use in prayer" has to be one of the archest lines in all of literature. I'm with Romeo. I'd fall in love with that.
In short, now that I'm an adult, I appreciate the young lovers a good bit more than I did when I was their age. This may be counterintuitive... but it also seems to be one of the main points of the play itself.
A number of Rosenberg's commenters noted that Romeo and Juliet is deliberately about young love. This is no doubt true. But the play is also, and insistently, about age. The fact that Juliet is 13, for example, is not just mentioned once. It comes up again and again. Moreover, the first time Juliet appears on stage, her aged comic Nurse launches into a rambling anecdote about when her charge was a toddler, an anecdote that Juliet clearly finds both tedious and embarrassing. Juliet's youth, then, is adamantly established, and also adamantly presented as a source of fascination for the elderly.
Old/young remains an obsession throughout the play—but that obsession does not, interestingly, work in any single way. Sometimes, being young means being rash and changeable, as when Romeo switches his hyperbolic affections from Rosalind to Juliet. Sometimes, it means being a hope for the future—as when the Friar marries the couple to try to end the feud between Montagues and Capulets. There are passages where old and young are presented as almost different species, as when Juliet irritably declaims, " ...old folks, many feign as they were dead; /Unwieldy, slow, heavy and pale as lead."
And then there are moments where it seems like old and young don't really act all that differently. Juliet's hasty marriage to Romeo, for example, isn't much more precipitous than Lord Capulet's sudden decision to marry her to Paris. And Romeo's affections aren't any more changeable than those of the nurse, who, having cheerfully helped Juliet marry Romeo, just as cheerfully advises her to forget that first marriage and turn polyandrist by wedding as her father wishes.
Rosenberg might argue that even the adults behave like kids in Romeo and Juliet because the play itself is childish. But... is Capulet really childish? Is the nurse? Surely, you don't have to be young to be precipitate or fickle. Adults behave like children with some frequency. And—if having sex is considered to be adult behavior—vice versa.
