Otako greets Galko when she enters the classroom, but Galko doesn’t open her mouth and responds by gesture.
Galko finally opens her mouth when Otako asks why she’s not talking.
She explains that she’s concerned about her double teeth because the main character in the movie was too.
I heard you can tear your hymen by riding horses.
سمعت أن البكارة قد تتمزق بامتطاء الخيول
Ich hab gehört, beim Reiten
kann das Jungfernhäutchen reißen.
Con la equitación se te 
puede romper el himen.
Con la equitación
se te puede romper el himen.
Il paraît que si on fait du cheval,
on risque de se déchirer l’hymen.
Ho sentito che l'imene potrebbe rompersi
 andando a cavallo.
Ouvi dizer que andar a 
cavalo pode partir o hímen.
