When I was young, I had a friend who is deaf and mute. It amazes me how she can predict what is happening around her. For example, if there are cars behind her or someone standing behind her. There was once incident when we were playing hide and seek. She found all of us in less than five minutes because she said that she can feel our breathing. Also, they are aware with someones emotion as if like they can see it right through you. Maybe because they cannot speak so they know how silence can mean something. As I read the chapter about hearing it taught me that people who can't hear have the skills to anticipate their surroundings better than people who can hear. Vibration in their surroundings can help them a lot.
