And I get that, I do. I just think that drawing the lines between this thing or that activity or this whole other thing is kind of silly. It's all sex. It all does what sex is meant to do, which is: Be awesome. The only way you know you did it wrong is if it wasn't totally awesome, and if that happens you should try some other ways and keep practicing. The only reason Full-On Doing It is such a huge Rubicon, no-way-back, now-you're-a-human-adult deal is because pregnancy is a huge deal -- everything else, especially in this day and age, is just social cosmetics.
Meanwhile dumb Jenny is like, "I've never heard of Dirty Dancing!" and dumb Serena is like, "You should download it!" And the fifty-year-old jowly grandfather who wrote that exchange sat back in his leather rolly-chair and thought, "Yes, that is a totally realistic conversation. Kids these days!"
Which doesn't distract from the awesomeness of this scene, which is wonderfully acted. You can really see S pretending to be the caring big sister, which because of the secret of Serena, means she actually is this caring big sister. Her fears and love for Jenny spill out over the edges of the pretense in really subtle, gorgeous ways. They both do a great job.
So Jenny explains to S in very small words that Damien is the right guy, and S can do no more than lie and say she supports Jenny's decision. Then she goes, "Obviously you're not going to school today, and you should commemorate today, so how about our boyfriend Nate takes you to lunch?" Nate's like, Um, whaaaa but goes with it. Being that she has to get ready for Chuck's thing, so why not make it totally awkward and have the love of Jenny's life take her to a lunch in celebration of Jenny's Blossoming Womanhood. SERENA PLAN!
