Today, I got tricked by the light. Doing research for a morning meeting, I promised myself that I would leave before dark. Working away, I kept one eye on the window for the impending twilight. As the last rays of the sun were setting, I made good on my promise to leave before dark. As I was turning out the lights I glanced over at the clock and realized it was almost 7:30! I should have know it was late when the cleaning crew wandered through and they were vacuuming the neighboring offices, but it never dawned on me to look at a clock.
I guess I need to start paying more attention to the time since I can no longer rely on the evening sky as an indicator of when I should leave!
