Troy loved his headphones. He wore them all the time. Noise canceling, with incredible dynamic range. He bragged that they cost a month’s rent and were worth every penny.
That’s why he just sat there when it happened, staring at his screen, typing lines of code and drinking his Mountain Dew. He didn’t hear the alarm, nor the screaming, nor all the shooting. He didn’t notice his cube-mates fleeing into the basement tunnels to lock themselves in.
He just sat there in his cubicle, clicking away and listening to Avenged Sevenfold at top volume right up until he was killed.
