Do you ever talk to yourself when alone? Mutter “good God” when you read a stunning twist of plot in a book or shout “holy shit!” when you open a bill? Do you swear aloud after an argument on the phone? Have you ever threatened a telemarketer after hanging up? Do you struggle with your private thoughts and discuss them with your loved ones at night as is considered healthy? Do you have friends that you discuss your private thoughts and ideas in your home? Does your subconscious cause you to talk in your sleep? Everyone does one or more of these things.
