What are you talking about?

Yesterday, I was talking to one of the girls up front about how i wanted to take some time off but i wasn't sure if the boss was going to let me. So the front desk girl says, "Well, you know their is only one person around here who can come and go as they please and you know who that is?" So i go,"MmmmHmmm!" I had no idea who she was talking about. So then she kept going on about this "mystery person" while i am trying to figure out who she's talking about. I can't ask her who she's talking about because then i will look like an idiot. So i just keep nodding, and throwing in a couple of meaningless phrases.Totally oblivious as to who we were talking about.
