A Moment of Panic...

I've seen movies for years where the bad guy/gal approaches someone from behind with a thin filament stretched between both hands to garrote the unsuspecting victim.
A couple days ago, I was sitting in the dentists chair, filled with apprehension.
I glanced at the instruments of torture in the tray next to me and in the reflection of the mirror there, I saw the hygienist  stretch the string of material between her hands and approach me from behind.
I quickly planned, the gun in my pocket would be difficult to get, the pick on the tray might be my only option.
She then stepped beside me, moving the tray away with her elbow.
"Floss is still a foreign concept to you, isn't it?", she said, as she saw the panic in my eyes.
