Truth being said

From Something Wicked This Way Comes by Ray Bradbury

Some nights, abed, Will put his ear to the wall to listen, and if his folks talked things that were right, he stayed, and if not right he turned away. If it was about time and passing years or himself or town or just the general inconclusive way God ran the world, he listened warmly, comfortably, secretly, for it was usually Dad talking. He could not often speak with Dad anywhere in the world, inside or out, but this was different. There was a thing in Dad's voice, up, over, down, easy as a hand winging soft in the air like a white bird describing flight pattern, made the ear want to follow and the mind's eye to see.

And the odd thing in Dad's voice was the sound truth makes being said. The sound of truth, in a wild roving land of city or plain country lies, will spell any boy. Many nights Will drowsed this way, his senses like stopped clocks long before that half-singing voice was still. Dad's voice was a midnight school, teaching deep fathom hours, and the subject was life.

It is different when you're being addressed directly, for then you have to react (and maybe repent) and can't muse.
