I heard a study once that said that people talk to themselves more than others 95% of the time. Sounds like a lot to me.

I wonder, are they ruminating? Intellectualizing? or Intellectualizing about their ruminating? Or trying to intellectualize away from ruminating?

Or practicing yelling at someone. I saw someone while I was out today talking away to themselves, so I couldn't help but wonder. No cell phone, no ear piece, on a bike.
