In my English class, there is a young boy who never talk. The boy, Michael, simply does not talk in class. No matter so much talking is occurred around him, Michael is never affected. Instead, he sits quietly at his desk and listens attentive to the rest the students talking and the teacher speaking. One day, Michael was surprised us all by raising his hand.
