Fear of communicating??

Who is really afraid of communicating to who? Is it a deaf person who fear communicating to a hearing person? Hard of hearing person who fear communicating to a deaf person? Or a hearing person who has a fear of communicating to a deaf person? Where does this fear lie? Why does this happen? Who exhibits this terrifying fear of communicating? Scared to strike up some real conversations when there is no real communication access? Why wait for an interpreter if there's an alternative way to communicate? Is it a fear of communication or a lack of understanding? How do you categorize yourself as? Are you an extrovert? Introvert? Shy? Weak?  Is it "communiphobia" (fear of communicating) you have? Is this something you notice in other people? Tell me your thoughts!
