A girl is not feeling right now, people could see it from her pale oval face. "What's wrong with you? Are you sick?" her classmate asked kindly. The girl nodded and refused to explain more.
In the corner, the girl's legs were curled beneath her in a fetal position, her instinct of self-protection, obviously. "Relax, relax, relax, it's not a big deal. I'll be fine soon." she encouraged herself to tolerant the pain，it's countless time that she has done so.
"How could I express my feelings to others when language description is useless? And I'm tired to say this plain seems like killing me again and again." the girl rested and tried to convey her abstract emotion into something more straightforward.
"If a nurse pricks my finger and draws blood, the moment my blood is out, the syringe has been corroded into a piece of the ice-cold black plastic ball with chocking smell fills in the air. Then everyone would know how my bone and muscle feel pain currently because they are eaten by a strong continuous attack." the girl thought about this and felt kind of relieved.
Meanwhile, people are still busy working around the girl till the choking smell reminds them something has happened. The only thing they see is a piece of an ice-cold black plastic ball in the corner. The girl has gone.
