Talking to oneself is good for the logical brain and impulsive mouth to sort themselves out. Whereas the brain says with its usually confident flair, “If she skips class, she’ll miss out on an important class session that will help determine how well she does on the midterm.” The mouth will then retort rather snappishly: “It’s freakin’ seven in the morning! She only got three hours of sleep last night! And it’s just one class she’s missing…”

Oh, wait, bad example. Let’s try this one:

Brain: “I think you need to find a job soon. Look at how much money you’ve got left.”
Mouth: “I’m looking.”
Brain: “Not hard enough, I don’t think.”
Mouth: “Oh, shut up. You think it’s easy to find a job with the kind of economy we’ve got right now?”
Brain: “For cripes’ sake. You’re a college student! I figure any kind of job will do for now. It’s not like this is an entry-level job at some newspaper. That’s the kind of job you want someday, right?”
Mouth: “You mean magazine.”
Brain: “Whatever. They’re all the same to me.”
Mouth: “Yeah, that figures.”
Brain: “Excuse me?”
Mouth: “Nothing.”
Brain: “Look, smart mouth…”
Mouth: “‘Bout time you realized I was. Now stop bothering me - Eyes and the MetaCarpal department are helping me with this project, and practically every other joint in this organization.”
Brain: “No need to get huffy.”
Mouth: “I only get huffy when you don’t function properly.”
Brain: “At least I haven’t gotten smacked yet!”

Hmmm - I guess both situations would apply to any one homo sapien. It’s too bad we can’t keep transcripts of these conversations.
