Read this to yourself. Read it silently. Don't move your lips. Don't make a sound. Listen to yourself. Listen without hearing anything. What a wonderfully weird thing, huh?
NOW MAKE THIS PART LOUD! SCREAM IT IN YOUR MIND! DROWN EVERYTHING OUT. Now, hear a whisper. A tiny whisper.
Now, read this next line with your best crochety- old-man voice: "Hello there, sonny. Does your town have a post office?" Awesome! Who was that? Whose voice was that? It sure wasn't yours!
