I am talking to myself out loud. A lot.

Usually if I do this, there's a purpose. For example, I'll say (out loud): "don't forget to take the trash out," and it helps me to remember... at least, I pretend it does. When I get busy, however, my self-talk gets briefer and - I would guess - makes less sense to the outside listener.

Just now, I caught myself doing a mental checklist and saying "okay" after each item. If anyone was listening, I would sound completely insane.

Uh, luckily, I don't think anyone is eavesdropping on me. If I did, there would be other issues to discuss.
