Conversing with Deaf and Hearing in the Same Room
Four people are sitting around the table enjoying a pleasant conversation. One is deaf, the other three hearing. Make sure to always include the deaf individual in the conversation by using sign language. Otherwise you are completely excluding one person from the discussion.
Use your newly learned skills to include that deaf individual at all times. When you speak, use sign language for the deaf, and your voice for the hearing. Anything less would be both rude, and wrong.
