[Scene: Outside Chris's bedroom.  Cytherea is sitting on a bench, trying to
read a book.  Unfortunately, there ARE distractions...]

[From within:]

Chris: YES! YES! YES!

Childra: Don't stop!  PLEASE don't stop!

Chris & Childra:
AAAAAAAAAAAAAAAAARRRRRRRRRRRRRRGGGGGGGGGGGHHHHHHHHHHHHHH!!!!!!!!!!!!

Cytherea: [To herself] <That's it.  For crying out loud, I'm only TWELVE!>
[Slams her book shut and storms into the bedroom]

[Scene: Inside the bedroom.]

Childra: Stop that RIGHT THIS MINUTE!!!

[Chris & Childra stare at her.  They are at Chris's desk, fully clothed,
poring over a large book.  Sheets of used paper and empty coffee cups are
everywhere.]

Chris: [Sighs.] I suppose you're right. I'd better get some sleep before
that midterm...

Childra: [Takes off the spectacles she's been wearing...] Me too.  I'm pooped.

Cytherea: [Very confused] Wha? I thought I...  You... This... But... What's
going on?

Childra: [Blinks.] I thought I'd told you.  Integration by Parts.

Chris: It's this stu...  <Sorry forgot about the Exon Bill> dumb problem.
Looks so simple, doesn't it?  Integrate dx/(x^4 + 1) by factoring the
denominator as a difference of squares...  Well, I do that, then sub in
x=tan(theta), and it all seems to go well until a certain point, where it
just STOPS.  I can't seem
to get past a '+2' term...

Cytherea: You mean... When you guys shouted 'YES!'...

Childra: [blushes] Well, we DO tend to get a bit excited over integrals...

Cytherea: And the 'Don't stop!' was...

Chris: [finishing her sentence] ...just our pleadings to the mathematical
muse, to grant us an elementary antiderivative.*

Childra: Before you ask, the final scream was just an expression of our
disappointment.  I'm sorry if we interrupted your reading.

Cytherea: But... I thought...  Sorry, but I thought you guys weren't being
quite that pure in here...

Chris: [Frowns] Cyth, I thought I'd given you more PROPRIETY than THAT!

Childra: Shame on you!  You're only twelve, lass! You shouldn't be thinking
of those things!  Take your mind out of the gutter, and back into books,
where it belongs!

Cytherea: [Confused] H-Hai... [Walks out in a daze...]

[The door to the bedroom closes.]

Childra: [To Chris] Now, where were we? [Chris grins...  <and leaves the
rest to your fertile imaginations...>]
