His mind goes blank and for an instant he sees nothing but pure white. Before he knows it, his papers are scattered on the floor and his desk is lifted in his hands. He hurls it at the window, and the glass cracks. Far away, he hears the murmurs of his peers and the shouting of his teacher. He doesn't look behind him or at anything besides the window as he opens it and steps onto the bottom of its frame.
He doesn't jump, and he isn't pushed; the feeling of solid metal leaves his hands, and the slight tug of a missed grasp teases his shirt. The wind pushes against him, rippling his clothes and whipping his hair around. A silent ringing drowns everything out; freedom brings a smile to his face, a slight tug at the corners of his lips.
His emotions were not happiness or anything of the like, but rather of peacefulness. Finally.
