I Have a Dark Side

My co-worker, sitting at the workstation next to me has been relentlessly tapping her foot for the last five hours. One might venture to wonder if she was politely asked to stop, and she has been on multiple occasions. But this, individual, does not seem to possess the understanding or compassion that most people inherently possess. The dissonant tapping is slowly dissolving the locks and chains keeping the Beast within at bay. Almost mockingly the incessant tapping continues as if blatantly begging to be challenged.
I've quite fondly envisioned nailing her foot to the floor, and reveling in her screams of agony to bring respite to the torment I have endured these past five hours.
