A new teacher is staying after school grading tests for her class. When she glances out the window, she sees a student in an unfamiliar, old-looking school uniform, laying white powder lines in the schoolyard. The teacher steps outside to issue a warning, but the student is gone, and the white line continues into the school building. So she follows it inside to find the student...
she heard the sound of the heavy 
metal door to the rooftop opening.
سمعت صوت باب السطح المعدني
الثقيل للسطح وهو يفتح
hörte sie oben die schwere
Metalltür zum Dach gehen.
escuchó que la puerta de metal
de la azotea se abría.
escuchó que la puerta de metal
de la azotea se abría.
elle entend le bruit de la lourde porte
en métal qui mène au toit.
la giovane sentì che la pesante porta di metallo
che portava al tetto era stata aperta.
ela ouviu o som de uma porta 
de metal pesada ser aberta no terraço.
