[SCENE: A brightly-lit classroom, its capacity greater than the number of students it contains. At the front, a chalkboard, on which the teacher is writing out Japanese verb conjugations. The clock ticks. The class dozes.
A buzzer goes.]
TEACHER: Alright, guys, fifteen-minute break! See you back here afterwards.*
[The STUDENTS file out, stretching, settling into conversation. Camera focuses briefly on the TEACHER, now erasing the chalk from the board.
Cut back to the classroom. STUDENTS are starting to filter back into the classroom, among them REI, clutching a cup of coffee in each hand and her purse under her arm. She starts to speak, but is interrupted by a noise coming from a small green box set into the wall.]
REI: Is that...?
[Heads begin to turn. Camera slowly pans back to TEACHER, who is now patiently vacuuming the dust off the chalkboard eraser. With the box. Set into the wall.]
REI: [sinking slowly back into her seat admist a chorus of muttering] ...wow. [scrambling for appropriate Japanese vocabulary] す...すごい！
TEACHER: ...is it? What, do...do they not have these where you come from?
*This scene takes place in the Japanese language class in a university in Kyoto, so our teacher wasn't actually speaking English; I have translated for the benefit of my audience, and also to spare myself the embarrassment of forgetting exactly what she said in the original language.
