Public school rules.
They will literally cut your hair if it's long enough, cut your pants/skirt (uniform) if it's too tight, take your shoes if it's not black and white. The rules may be different depending on the school but mostly the same.
i can feel you, back in Secondary school we all experience that cutting hair for military looks and i found that foul because being a student we have the right to choose what hairstyle we wanted.
and must not be forced to have their style that Sucks really.
the racism
