Ring the Alarm

I got to work early this morning and nobody was there, and instead of just going into the office, I stood outside for forty-five minutes looking anxious because I was afraid I'd set off some kind of crazy alarm and force a mass evacuation. I made the mistake of blurting this out when the first person arrived, thereby winning the award for most awkward new employee ever. (I didn't force everyone to flee the building, though. Success!)
