Heard about this LA Times article from the Speak Up Librarian blog.
My Turn: Hearing-impaired people need friends and some patience
I especially connected with this paragraph:
Even our friends are selected carefully. We cultivate friendships based on who is sensitive to our needs. They are the people who are willing to speak a little louder and more distinctly. They are the people who are willing to repeat themselves if they see from your expression that you didn't hear all that was said. They don't wait for you to apologize or "phase out" of a difficult-to-hear conversation. They make sure that you never feel ashamed because of your disability.
