Talking to Myself

I was on my way to get coffee today and evidently my department head was watching out his window as I headed down the skywalk. Later he asked me if I was singing or having a conversation with myself. It took me a minute to realize I had been talking through some dialogue for the story I'm currently working on at the time he saw me. Thinking back, I now realize I do this a lot. The stories are a constant in my brain that I have to consciously block out when I need to do something else. One might say my imaginary friends are with me always. So nice not to be alone, isn't it?

Do any of you walk around talking to your characters?
