Speak out, and I am there. But to you, I have no inflection- just a spark that makes a connection. I can shake the walls if brought to anger. I can tell someone when you're in danger. I can break a heart or act a part. I can sing to the birds. I can carry your words. We will always be the same, you and I- when you are happy, I laugh, and when you are sad, I cry. A team, forever bound, whether or not you even make a sound.
What am I? Answer: Voice
