The over-worked, the dedicated, or the forgetful?

I went to K-Town a while back, to get a bite to eat, on a Sunday night. While walking in from the parking lot, I noticed that 2 of the offices had the lights on in the building across the street. At first, I felt bad for the people that were stuck in their offices, on a Sunday night, all by themselves. ...Then I thought, "That's dedication! Those people will get where ever it is they are going, because they are willing to go above and beyond to get the job done!" ...Then I thought, maybe they just left the lights on, as I walked into the Tofu House for dinner.
