Sitting in my office with the lights off, music playing, quietly working. A woman from another office walks in and announces, "My gawd, it's like a tomb in here!" as she flips on lights.
"But it's MY tomb, not yours. Please turn those off."
She turns off the lights, and leaves in a huff.
Ok, seriously, if I'm going to be here at this job every day while it slowly kills me, let me set up my tomb the way I want it.
