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. He was actually attempting to talk. Interesting and curious at that was going to happen when he got called on, we all leaned forward against our desks looking at him with our eyes wide open. There was total silence in the room as the teacher call aloud his name.
