L-double O-N-Y

Do you talk to yourself?  I do.  In the car, in the kitchen, at the mall, out loud and in my head.  When I catch myself talking out loud (That’s the second time in two sentences I’ve typed “out load” instead of “out loud”.  Issues.) and I’m not alone (walking down the street, through the grocery store, in the parking lot), I tell myself to cut it out, usually in some kind of crazy-sounding hiss.  “Stop talking to yourself!”  It doesn’t keep me from looking crazy.  I hope no one notices.  Is it weird?  Or normal?  I really can’t tell.
