You are a new student at your school. One time you were in the library, you saw a boy being laughed at from behind by a small group of other boys. The boy who is being laughed at is just silent while reading a book, his ears are always plugged in with headsets, you have passed this boy several times, but he never speaks or turns around when called. You don't know the reason he was made fun of like that, nor were you told that he was deaf.
