I had an interesting conversation with another librarian yesterday. She was joking around about how if a "crazy person with a gun" (as opposed to us non-crazies, huh?) came into the building we should tell them to take it up with the director and point them toward her office.
I said, seriously, "If a gunman comes into the library, I am gone. I already have a plan to get out of the building. I'm running for it." The reference desk is nowhere near the front door, so I like to tell myself I'd have a chance. On the other hand, someone with a grudge against "that mean little librarian" might save his rage until he got up to my desk. (try not to dwell on that one...I do.)
She seemed shocked. She was surprised that I'd have that reaction, that I wouldn't stay and assist the patrons in their escape. I laughed. When I am legally allowed to carry a concealed weapon (soon!), I will not be allowed to do so at work. My only defense is running. They don't pay me nearly enough to stick around.
