Why do you move your lips when you read?
IT is to get people to slow down and think about what they read. Things sound a whole lot different when you slow down and say it out loud instead of just scan a sentence and do a drive by posting.

But then you knew that, didn’t you?
So you just like to lecture people because you are morally and intellectually superior?
