Little facts about my life
Most people think if you're deaf that you also can't speak, but that's wrong. Deaf people have a voice box too, they just don't always want to use it.
Some people think if you talk louder and slower that deaf people will understand somehow... Nope, that won't work. In fact, the slower you move your mouth, the less likely a lip reader will understand. And talking louder will not make a deaf person understand. They will just look at you like you're an idiot.
Just because someone is deaf - doesn't mean they can't read and write English too. They have a brain too you know.
