Mental Reconstruction: The Office at 6 a.m. on Saturday

6 a.m. on a Saturday, you've come in to an empty office alone. When you badge in and step through, the automatic sensor lights come on only near the entrance while the inner half stays dark. A yellow sticky note is stuck to one monitor by the window, and a corridor with a refrigerator leads toward the pantry. On the glass wall of the meeting room, marker writing from last week's meeting still hasn't been wiped off.
