Good examples of this includes:
•"Amanda Pierce, in the cubicle to your right, has a six-year-old son named Jamie, who is autistic. Her cubicle is plastered from top to bottom with the boy!s crayon artwork - sheet after sheet of precisely drawn concentric circles and ellipses, in black and yellow. She rotates them every other Friday. Be sure to comment on them."
•"Barry Hacker's wife was two months pregnant at the time, and lingered in a coma for half a year before dying. It was a tragic loss for Barry Hacker. He hasn't been himself since. Barry Hacker's wife was a beautiful woman. She was also completely covered. Barry Hacker did not have to pay one dime But his dead wife haunts him." (note referencing work benefits in midsft of tragic lore-telling)
•"Kevin Howard sits in that cubicle over there. He is a serial killer, the one they call the Carpet Cutter, responsible for the mutilations across town. We're not supposed to know that, so do not let on.... Kevin Howard does not let any of this interfere with his work. He is, in fact, our fastest typist." (though he is a serial killer, that is okay since he is a productive worker!)
Notice the casual tone that is set in the dialogue, as well as how quickly the person giving the tour moves on after giving such harsh backgrounds; I find this to amplify the workers' insignificance..
