I was Office Max today, looking at spiral notebooks, minding my own, when I heard an employee say "sir". I immediately turned around without thinking, prepared to say something in return, but it turned out, he was talking to a customer on the phone.
My question is, have any of you guys ever gotten so into a male mindset that you don't have to think twice about responding to "sir"? I found it odd, because just a few weeks ago, I accidentally referred to myself as a girl, and now I'm just automatically responding to "sir".
