I am a really weird person. I always think that. Sometimes I think myself actually is a small bunny, or a smart fox. Is the world I see every day true? Is the red actually red? What if there is something that we all can't see? Will they hurt us? These questions seem so silly and strange, but I am just not sure about the world. My mom said that I was short of the sense of security, and I agree with that. I am afraid people around me will kill me one day suddenly. And also, who am I?
