Seriously, I talk to myself quite often at the office (though I’ve gotten better at keeping the internal dialog internal) or I’ve got a podcast going or iTunes or Sirius–there is almost always something making noise in my office (other than the space heater). It’s when I turn everything off and silence reigns that you should worry. And run. Because quiet means I’m so absolutely ticked off at something (or someONE) that I can’t even abide the sound of music. That’s some serious anger. Talking to myself just means mild confusion or something I have to work out. But singing along to the music is the best sign.
